CELTIC LANGUAGE ELEMENTS IN THE PLACE NAMES OF IRELAND

The article deals with the culture and heritage of ancient Celts by analyzing the toponyms of Celtic origin in the Republic of Ireland, Northern Ireland, as well as in the places where the Irish diaspora is present. In accordance with the set goal, the article considers the cultural component in the meaning of linguistic units and the classifi cation of toponyms and their use in diff erent parts of the island. By the example of the analysis of the meaning of Celtic toponyms functioning in modern Ireland and Northern Ireland, it is shown that Celtic national heritage has not been lost. The study of toponyms allows us to penetrate into the worldview of the ancient people whose culture infl uenced and shaped the descendants of Celts. Key words: Celtic languages, place name, toponymy, Ireland, the Irish language, semantics.

ISSN 0320-2372. ІНОЗЕМНА ФІЛОЛОГІЯ. 2020. Випуск 133 is present. Our further goal is to draw a classifi cation of toponyms and to analyze cultural components in the meaning of these linguistic units.

Methodology (Methods and Materials).
We applied the qualitative research analysis to develop an in-depth understanding of the etymology, use and semantics of place names in Ireland which come from the Irish language. Based on this method, we revealed who named certain places (Anglo-Saxons, Vikings, Celts, etc.), when they were named (pre-Christian times or Christian times), why they were given this particular name (geographical features, legendary heroes, deities, man-made objects located there, etc.), what these names mean, what kind of a feature they refl ect, where these names come from, i.e., their etymology (referring to either a language or region of origin) and where they are located. In many cases, answers to some of the questions could not be found, since much time has passed since the naming and/or the necessary documentation (if it ever existed) has disappeared.
More extensive scrutiny of the data has revealed further telling facts that could not have been discovered without a quantitative analysis. Referring to The Placenames Database of Ireland, we have provided statistical data of Irish place names in various parts of Ireland. We have analyzed the percentage of established Irish place names in diff erent parts of the island, interpreted the investigated data and provided reasons for such results. All the relevant materials were taken from The Placenames Database of Ireland.
Results and Discussion. The Celtic languages are a group of related languages that are part of the Indo-European language family. Once the Celtic languages were spoken in large areas of Western and Central Europe; now they are preserved mostly in Ireland, Wales, Brittany and Scotland and are spoken by around a million speakers in total [4, p. 45].
The ancestral home of the Celts is known to be localized in Central Europe. We know relatively little about the ancient stages of development of the Celtic languages, since the monuments of that era are very scanty and not always easy to interpret. However, the data of the Celtic languages, especially Old Irish, play a crucial role in the reconstruction of the Indo-European proto-language.
The Celtic languages are divided into ancient and modern. The ancient ones cannot be restored anymore, while the modern Celtic languages are the ones that are either still used or have only recently become extinct (for instance Cornish or Manx).
In terms of the internal genealogical classifi cation, the Celtic languages are divided into Continental and Insular. The Continental Celtic languages are all extinct, primarily due to the assimilation into the Roman culture, while the insular Celtic languages are still alive. Within the latter, two groups are diff erentiated: Goedelic languages (Irish, Scottish and Manx) and Brythonic languages (Breton, Cornish, and Welsh). These two groups of Insular Celtic languages are not intelligible with each other. However, there is some degree of intelligibility, since they evolved from a common ancestor [7].
In view of the fact that the Celtic languages were once spread up to the Balkans and Western Ukraine, needless to say that the Celtic substrate played a certain role in the development of many languages across Europe. The Celts were among the fi rst in Europe to process iron. For example, the Germans borrowed the word "iron" from the Celts (Irish iarann). Traces of Celtic infl uence can be tracked down in the Basque language. There is also the hypothesis supported by W. Keller, I. Dal, G. Visser, W. Preusler, P. Poussa and other scholars that the Celtic substrate was of greater importance for the development of the English language than it had been previously thought, namely up to the beginning of 20th century. For example, the Celtic infl uence is attributed to the appearance of extended times in English, such as I am reading. A number of words from the Celtic languages denoting specifi c realities (e.g., druid, kayla, clan) have entered many other languages. There are numerous celticisms used in English all over the world which have a Celtic origin. Among them, such lexical items as bog, clan, glen, gob, loch, whiskey, hooligan, boycott, shamrock that derived from Irish.
The Celtic element is still prominent in Ireland today, especially in proper names places, i.e., toponyms. As known, toponymy is a branch of onomastics which studies origins and meanings of place names, their use and typology [2].
Toponyms can be divided into geonyms, that is, proper names of all geographical objects on the Earth, and cosmonyms, or proper names of cosmographical objects outside the Earth. In this article, we will not address the cosmonyms, which will be analyzed in our further research.
Toponyms are considered to be the most stable layer of the language vocabulary. Place names are valuable historical sources containing important information about the history of a certain area as well as about the people inhabiting it and, obviously, about their culture.
Language contact in Ireland. Toponyms of any linguaculture have developed in the process of natural historical development and always unite sources of several languages. Irish place names are not exceptions as they trace their ancestry to several languages. This can be explained by the fact that Ireland has always been an extremely culturally and linguistically diverse place. Some of its languages were used only by small groups and some only existed during a limited time. The two languages which have the longest history and still exist today are, certainly, Irish and English. However, it is important to examine how other languages are manifested in the Irish toponyms.
Along with the Celtic elements in the Irish toponymic structure, there is a signifi cant layer of Scandinavian borrowings, a layer of French elements and other minor borrowings which we will further consider.
Norse names in Ireland. The Scandinavians founded most Irish towns which are situated at the estuaries of major rivers. Dublin and Belfast are two exceptions; the former city predates the coming of the Vikings and the latter is a new settlement from the beginning of the 17 th century. In some instances, the English names of towns are derived from the Norse names and are not related to the Irish form: Loch Garman -"Wexford", Port Láirge -"Waterford", Ant Inbhear Mhór -"Arklow". Three of the four provinces of Ireland have a second syllable from Norse staðr -"place" (or possibly from a combination of genitival s + Irish tír -"country"): Munster, Leinster, Ulster. The fi rst syllable is derived from a name for the tribe which lived in the area designated as is the entire form of the fourth province, Connacht [12].
Anglo-Norman names. The number of Norman place names is remarkably small, especially considering the large amount of Norman surnames, which became established in Ireland, and numerous loanwords in Irish from the Norman invaders. One reason might be that the Normans did not establish towns. Instead, they built keeps in the countryside and ruled from fortifi ed castles. But even there few Norman names can be found. Possibly, it is due to the acceptance by the Normans of the names which went with the territories occupied by the Irish. Since the Normans were concentrated in the south of Ireland, there are names which derive from the province of Munster and a point of the compass: Ormond <Iarmumhan -"east Munster", Thomond <Thiarmumhan -"north Munster" and Desmond <Deasmumhan -"south Munster," the latter later forming a common fi rst name in Ireland [12].
Statistics on the use of Irish today. The Central Statistics Offi ce (CSO) published the Census 2016 report, Profi le 10 -Education, Skills and the Irish Language. It shows that 1.76 million people (aged 3 and over) indicated that they could speak Irish. This constitutes nearly 39.8 % of the population. There was a slight decline (-0.7 %) in 2011.
It should be noted that Gealtacht, i.e., Irish speaking areas, are more likely to use Irish in their daily conversation. It should also be noted that Gealtacht areas have a much higher percentage of established Irish forms of place names. These regions are historically continuous areas on the western seaboard of Ireland, where the oldest form of the Irish language can be heard till present. As it is clearly shown from Fig. 1 below, such counties as Sligo, Kilkenny, Galway, Waterford, Mayo, Kerry, Longford, Wexford, Limerick and others have a very high percentage of established Irish forms of place names. The Gaeltacht of these counties consists of numerous native Irish speaking communities.
On the contrary, the counties of Londonderry, Armagh, Antrim and Cavan, which are located in Northern Ireland, report to have only 24-38 % of established Irish forms of place names. We used a database of administrative place names, including town lands, parishes, names of urban centres, etc., taken from the The Placenames Database of Ireland (https:// www.logainm.ie/en/) project. It was created by Fiontar & Scoilna Gaeilge in collaboration with The Placenames Branch (Department of Culture, Heritage and the Gaeltacht). This is a comprehensive management system for the data, archival records and place names research conducted by the State [14]. We have studied a fairly detailed map of Ireland and noticed that there are certain lexemes and morphemes that appear over and over again in many places names throughout the Republic of Ireland and Northern Ireland. It is not uncommon in other cultures. For instance, English suffi xes -borough, -pool, -ham, -cester, -town, French --ville and German --burg can be still seen today.
Until the early 17 th century there were very few towns or big settlements in Ireland. The situation was not peculiar solely to Ireland -it was so almost everywhere else at that time. Thus, notable features of the landscape, such as cliff s, hills, rocks, fi elds, meadows, valleys, lakes, islands, and rivers gave rise to place names. For instance, the name of the capital city of Dublin derives from the Irish word Dubhlinn from dubh meaning "black, dark", and lind -"pool", referring to a dark tidal pool. This tidal pool was indeed located in Dublin where the River Poddle entered the Liff ey. Baile Átha Cliath meaning "town of the hurdled ford", is the common name for Dublin in modern Irish. Áth Cliath is a place name referring to a fording point of the River Liff ey. By the Dublin example, it is clearly seen how geographical features gave rise to place names.
In the later years, the historical and technical development had led to the construction of numerous bridges, castles and churches which was manifested in new place names with the corresponding affi xes appearing. We have compiled a list of some of the most common place name elements in Ireland. They are to a great extent anglicized Irish language names. The anglicized spellings of the Irish words are provided below together with the words' etymologies [11].
1. Agha, aghy, aghey, augha -the word achadh means "fi eld" in Irish. The place names bearing this prefi x are villages of Aghalee (Northern Ireland) and Aughagower (a rural county of Mayo, Western Ireland).The geographical features of these sites totally refl ect their names.
2. Ath -the word áth meaning "ford". The name of the city of Athlone in Irish is Baile Átha Luain meaning "The town of Luan's ford". It is a town in Westmeath County, Ireland, which is located on the River Shannon. Since a ford is a shallow place with good footing where a river or stream may be crossed by wading, or inside a vehicle getting its wheels wet.
3. Ard meaning "high" or "height" in Irish. This usually means a physically high place, but it can also be referred to a place of importance and high status. A bright example is the High King of Ireland who was addressed as the Ard Rí. Some notable places having this lexeme or prefi x are found in the following place names: the Ards Peninsula (county Down), Ardstraw (county Tyrone), Ardfert (county Kerry) from Ard Fhearta meaning "High Burial Place". It is worth noting that the word Fearta is often used for a burial place in reference to a site of pre-Christian burials. Some other examples might include Ardagh or Ardach meaning "high fi eld" and Ardmore (Aird Mhór).
4. Mor or mhor means "big or great"; in a word combination with Ard it means "great height". This may seem odd if you are in Ardmore in Waterford, which is a seaside town. But there are high cliff s and hills around it with the monastery and cathedral which gave the town its name.
5. Bally, Ballyna, Ballina Bally is an extremely common prefi x in town names in Ireland, which is derived from the Gaelic phrase Bailena, meaning "place of". It is not quite right to translate it as "a town of", as there were few, if any, towns in Ireland at the time when these names were formed. An example of a town with this prefi x is Ballinasloe from Béal Átha Sluaighe meaning "ford mouth of the crowds". Indeed, there is a river to be forded here, which explains this particular name. Bealach is an Irish word for "pass" ISSN 0320-2372. ІНОЗЕМНА ФІЛОЛОГІЯ. 2020. Випуск 133 or "passage" and can be come across in small towns Ballyclare (Northern Ireland) and Ballaghmore (County Laois).
6. Beg means "small" in Irish and is used at the end of a name. It often implies that a certain geographic feature is a smaller one out of two adjacent features, for example, Killybegs (county Donegal), Lambeg (county Antrim). North of Lough Neagh is the Ireland's largest lake, while there is a much smaller lake called Lough Beg. 7. Bel, bell. The name Belfast derives from the Irish Béal Feirsde, later spelt Béal Feirste. The word béal means a "mouth" or "river-mouth" while feirsde/feirste is the genitive singular of fearsaid and refers to a sandbar or tidal ford across a river's mouth. 8. Ben, bin. Irish binn/bean meaning "peak". Binn occurs in Binn Ghulbain (Benbulbin) in Co. Sligo, Benbaun (Binn Bhán), Beenoskee (Binnos Gaoith) and Binevenagh (Binn Fhoibhne). Its equivalent in Scottish Gaelic is beinn, which appears in many Scottish mountain names, such as Beinn Nibheis (Ben Nevis) and Beinn Macduibh (Ben Macdui). 9. Bawn. It is the anglicized version of the Irish word badhún meaning "cattlestronghold" or "cattle-enclosure." Its original purpose was to protect cattle during an attack. The remains of a late medieval bawn and the defensive wall surrounding an Irish tower house can be seen at Bawnboy House, which is the origin of the village name. 10. Bun means river's bottom/foot/mouth and can be seen in Bundoran. 11. -bridge. When found at the end of a name, it implies that the town developed beside a bridge or became famous as a bridging point. These town names are usually of English language origin. For example, Banbridge (county Down) which grew up around a bridge over the river Bann. Newbridge (county Kildare) grew up when a bridge over the Liff ey was built at that point (Newbridge is increasingly being called Droichead Nua, which is a Gallicized version of the original English name.) Such names illustrate the importance of bridges to trade.
24. Carrow, carry from Irish ceathrú for quarter, e.g., Carrowdore, Carryduff . 25. Cashel from caiseal meaning "stone ring-fort, a circular defensive fort" (Cashel, Tipperary; Cashel, Galway). An Caiseal (anglicized as Cashel) is a small Gaeltacht village on the east side of Achill Island in County Mayo, Republic of Ireland. As this is a Gaeltacht village, the Irish AnCaiseal is the only offi cial name. The anglicized spelling Cashel has no offi cial standing.
26. Clon, Cloon. A Gaelic word meaning "dry place". This name is much more common in Connaught than elsewhere in Ireland. This is because Connaught is wetter, and, therefore, a dry and well-drained site was more valuable and well regarded. The examples are Clonmel (county Tipperary), Clonmacnois (county Off aly), and Clonfert (county Galway).
27. Dona(gh) from domhnach meaning "church," e.g., Donaghadee, Donabate. 28. Duff , duv from dubh meaning "black," e.g., Claddaghduff , Cloughduv. 29. Derry. This term evolved from the Irish name for "a place of oak trees" doire, or sometimes a grove or clearing of the same. Oak trees are found in many places in Ireland, and because of this there are many examples of the name Derry. The most famous place to have this name is Derry city (county Londonderry). Other examples include Derryaghy (county Antrim), a former village which is now part of Belfast city, as well as Edenderry (county Off aly).

31.
Droichead. An Irish word meaning "a bridge". The prime example is Drogheda (county Meath), which is an evolved spelling derived from the Gaelic word. There is also a town of Droichead Nua -"New bridge" in Kildare county. 32. Drum, drom. A Gaelic word meaning "a ridge". Examples include Dromore -"The greater ridge" (county Down & Tyrone), Drumquin -"Quinn"s ridge" (county Tyrone), and Drum -"the ridge" (county Monaghan).
80. Orla, urlar from urlár meaning "fl oor/fl at land," e.g., Stranorlar, Urlar. 81. Vea(gh), vei(gh) from bheithe meaning "of birch," e.g., Ballyveagh. Mythological fi gures, legendary heroes and deities in place names. Mythology has always played a crucial role in the worldview of the ancient Celts. It is the whole cultural layer which infl uenced their life, household, mindset and perception of the world. Mythological elements aim at refl ecting the universal concerns of people throughout history. Both language and mythology link the mythical world with the real one and enable the direct connections between them.
A substantial amount of modern Irish place names are rooted in Celtic mythology: these are numerous names of gods and goddesses, mythical tribes and legendary heroes. Place and personal names together with ancient places of worship, statues, engravings and cult objects are valuable sources of information about Celtic deities.
Many Irish place names include the names of the gods and goddesses. The name of the country itself is derived from Éire (Ériu) -the Irish supreme goddess, one of the supreme goddesses of the Celtic pantheon. The very name Ériu translates as "abundant, fertile land" [10]. Eriu is also the goddess of fertility, prosperity and abundance.
"Land of Ana" is one more notable name for Ireland. In Celtic languages, the name Ana means "wealth, prosperity, abundance" [2, p. 16]. Later the name Ana (Anu) was transformed into Dana / Danu. She was considered to be the mother of the Tuatha De Danann tribes ("the tribes of the goddess Anu"), the legendary founders and rulers of the Kingdom of Ireland. Modern Ireland is often described with the epithets "prosperous, fertile", which confi rms these connections.
Irish Banba and Fódhla are sometimes used as literary names for Ireland. In Irish mythology, Fódla or Fótla (modern spelling is Fódhla or Fóla), daughter of Delbáeth and Ernmas of the Tuatha Dé Danann, was one of the tutelary giantesses of Ireland. Banba, a daughter of Delbáeth and Ernmas of the Tuatha Dé Danann, is also a patron goddess of Ireland. They could have been goddesses of war as well as fertility goddesses, thus refl ecting the pride of the Irish for their fertile lands.
A number of goddesses were deifi ed rivers, notably Boann (of the River Boyne) and Sinann (the River Shannon). Boann (Boínd, Boínn) is the goddess of water, fertility, inspiration and knowledge [2, p. 45]. Her name is interpreted as "white cow" (bófhionn) in the Dindsenchas, which is a class of onomastic texts in early Irish literature, recounting the origins of place names and traditions. The longest river on the island -the River Shannon -bears the name of the goddess Sinann, the granddaughter of Lir, god of the sea. She is associated with Connla's Well, a mythical spring which is a source of inspiration and deep wisdom.
There are toponyms derived from Irish mythology which are associated with the names of legendary heroes, for example, Echtge, a mountain chain named after a noble lady from the mythical Tuat tribe. According to the legend, mountain ranges served as a dowry of this lady. Hill of Allen is named after Allen -a daughter of the commander from the mythical Tuat tribe. Other place names consist of a common Celtic element and a proper name, related to mythology, for example, cnoc meaning "hill, mountain" -Cnoc Fίrίnne, Cnoc Meadha, Cnoc Sίdhe Úna; inber meaning "mouth" -Tuag Inber.
The etymology of Irish counties. There are 32 traditional counties of Ireland, both in the Republic and in Northern Ireland. They are named after Irish gods and goddesses, geographical features like rivers, plains and swamps, and man-made objects, like churches or castles.
The counties named after Celtic deities are Armagh and Louth. Armagh comes from Ard Mhacha, meaning "Macha's height." Macha was an Irish goddess associated with Ulster and Armagh, where she is said to have given birth to twins after racing a horse. Louth was named after the Irish god Lugh (modern spelling Lú). He is one of the most prominent gods in Irish mythology and is portrayed as a warrior, a king, a master craftsman and a savior [1].
Not only pagan gods and goddesses are present in Irish place names, but also Christian saints and martyrs. The name of County Wicklow comes from Old Norse meaning "meadow of the Vikings" [3]. The Irish name Cill Mhantáin means "Church of Mantan" and is named after a contemporary of Saint Patrick. A disciple of Saint Patrick, Mantan or Manton, is said to have assisted St. Patrick in his various labors. He had his teeth knocked out by Irish pagans. Hence he was renamed Mantan, which means "toothless one" in Irish. Cill Mhantáin was historically anglicized as Kilmantan.
Similarly, the name of County Roscommon comes from Ros Comáin, meaning "Cománs wood." It was named after Saint Coman, who founded the monastery of Roscommon around 550. The name of County Kilkenny derives from Cill Chainnigh, meaning "church of Cainnech." Saint Cainnech allegedly converted the county to Christianity in 597.
Geographical features of landscape form the foundations of the names of counties Sligo, Monaghan, Cork and Mayo. The Sligo county is named after the town of Sligo, which comes from Sligeach, meaning a "shelly place," a reference to the large amounts of shellfi sh to be found in the river and its estuary. The name of County Monaghan comes from Muineachán. "Muine" means "brake" (a thickly overgrown area) or "hillock," justifying the county council's interpretation of the name as a "land of the little hills." It could also derive from "Muine Acháin," "Acháin" meaning "fi eld," thus making up a "bushy fi eld" or a "hilly fi eld".
Both the city and county Cork's name come from corcach, meaning a "swamp" and providing us with the information about the geography of this place. County Mayo's name has its origin in Maigh Eo, meaning a "plain of the yew," i.e., "various species of trees." Centuries later, when a number of churches and cathedrals were erected, numerous cities, towns and counties report to have the component "church" in their names. Counrty Kildare, for instance, comes from Cill Dara, meaning a "church of the oak". One possible explanation is that the material churches were mostly built starting with the 13 th century, when the name of the county was established.
Place names of Irish origin outside Ireland: North America and Australia. The 19 th century featured massive emigration of the Irish due to the greatest loss of life in 19 th -ISSN 0320-2372. ІНОЗЕМНА ФІЛОЛОГІЯ. 2020. Випуск 133 century Europe -the Great Famine (1845-1849). About one million people died and a million more emigrated from Ireland, causing the island's population to fall by 23 %. Thus, the Irish communities were established in many towns and regions of the USA and Canada primarily, as well as in Australia and New Zealand to a lesser extent. The Irish named or renamed the places they lived in after places in Ireland. Since most severely aff ected areas by the famine were in the west and south of Ireland, where the Irish language was dominant, the people named new places in Irish. There are numerous cities and towns across the USA and Canada of quite obvious Celtic origin. The majority of place names trace their origin in Irish surnames as well as lexemes denoting geographical landscape. They are always anglicized versions of the Irish words. A town name that appears most often is Erin, anglicized from Éire (Erie) -the Irish supreme goddess, one of the supreme goddesses of the Celtic pantheon. A town name Dunmore (sometimes Dunmore) is often to be seen in diff erent American states, Canada, Australia and the Bahamas. The place name comes from the Irish Dun Moor meaning "great fort". Ardmore comes from the Irish Arid Moor meaning "great height" and is a name of 10 cities and towns in the USA, 3

towns in Canada and one in New Zealand
Irish surnames in place names outside Ireland. A town named Foley is derived from a surname which originated in Ireland, in the southeast Munster region. The name comes from the original modern Irish Ó Foggily meaning "plunderer." McMullen is a name for several American cities and a surname with predominantly Irish origins together with some Scottish history. It derives from root forenames such as Mao lain, Malan and Meal lain. All of these forenames have evolved over time to the collateral "Son of Mao lain", anglicized McMullen.
Killen is a name for several American towns and an ancient Irish surname of two possible origins. It may be an anglicized form of the Irish personal name Collin, a diminutive of Calash which means "bright-headed". The second possibility is that it can be an anglicized form of the Irish Mac Coiling, which is composed of Mac meaning "son of" and the personal name Colin, derived from the Celtic Chilean meaning a "young hound." The United Kingdom. There are many place names in the UK associated with legendary characters, for example, Edinburgh (Dùn Èideann, Èideann is the legendary founder of the city), Brega plain (in honor of a mythical prince), Mount Cúchulainn's leap (in honor of the hero of the epic -Cuchulainn [2, p. 117]), the coast of Baile's Strand (in honor of the mythical prince), the Beare peninsula (in honor of the mythical princess), Erne Wateray waterway (in honor of the mythical princess), etc. Ath Fodhla (the angliсized version is Atholl or Athole) is a large historical division in the Scottish Highlands. As mentioned above, Fódhla is a traditional name for Ireland and ath is an Irish prefi x meaning "second", "later". Thus, the name, originally Ath-fhotla, literally means "New Ireland" and appears in the Annal of Ulster, indicating that the Gaels or their language had arrived in the Pictish heartland by 739 A.D., and Atholl became a Celtic earldom [5].
The usage of Irish and Irish place names today. Starting from the 19 th and 20 th centuries till present, there has been a renewed interest in Celtic culture. This variety of movements and trends is often referred to as The Celtic Revival. There are cultural studies' programs at schools aiming to expose students to the rich cultural heritage of Irish folk and traditional music and song. Apart from that, there are numerous Celtic festivals throughout the country, television channels, radio programs, magazines and newspapers in Irish, poetry evenings and traditional Irish dances workshops. The Irish language is a compulsory subject in government-funded schools in the Republic of Ireland and there are up to 50 Irish-language summer colleges in the Gaeltacht every summer. There is a certain interest in Irish across the Altantic, mainly within the Irish diaspora which is quite numerous there.
Currently, most Celtic speakers live in the outskirts of Europe. There are also small colonies in America: Welsh speakers live in Argentina, whereas Scottish -in Canada. Native speakers of Irish are mostly concentrated in rural areas, living compactly (areas of Irish and Scottish languages are called Gaeltacht) [8].
Gaeltacht. Gaeltacht is an Irish-language word for any primarily Irish-speaking region. In Ireland the term Gaeltacht refers individually to any, or collectively to all, of the districts where the government recognizes that the Irish language is the predominant vernacular, or language of the home [16].
The majority of Irish speakers live in Gaeltachtaí, areas that are located mainly along the west coast of Ireland and number 82,715, of whom 76.3 % speak Irish. Living Irish called Gaeilge is spoken in Gaeltachtaí, areas in the far west of Ireland (Donegal, Erris, Connemara, Dingle, and Arran Islands).
The Gaeltachts are mainly coastal areas of Ireland where people lead a rural life. One third of all those who use the Irish language for everyday communication come from these rural areas. Authorities support the remaining Irish-speaking enclaves. Thus, at the initiative of the government, all English-language signs on the west coast of the country were replaced by Irish ones. In these areas, rivers, lakes and valleys can only be marked in Irish [8].
In March 2005, it was announced that the government of Ireland would begin listing only the Irish language versions of place names in the Gaeltachtaí as the offi cial names, stripping the offi cial Ordnance Survey of their English equivalents, to bring them up to date with road signs in the Gaeltacht, which have been in Irish only since 1970. This was done under a Placenames Order made under the Offi cial Languages Act.
The Offi cial Languages Act 2003 sets out rules regarding use of the Irish language by public bodies; it established the offi ce of An Coimisinéir Teanga to monitor and enforce compliance by public bodies with the provisions of the Offi cial Languages Act; and made provision for the designation of offi cial Irish-language versions of place names and the removal of the offi cial status of English place names in the Gaeltacht. The Act is being implemented on a phased basis [13].
The principal legal eff ects of a Placename Order are one or other of the following:  in respect of any place name outside the Gaeltacht, the Irish and the English versions of the place name have the same status and the same legal force and eff ect; and  in respect of a place name in the Gaeltacht, the Irish version of the place name has legal force and eff ect while the English version of the place name has none.
Any Placenames Order is without prejudice to private use of the Irish or Englishlanguage versions of a place name. In many cases, it is also without prejudice to public use of a place name.

Conclusions.
Following the main objective of our paper -to analyze the use of toponyms of Celtic origin, we have studied a detailed map of Ireland and noticed that there are certain lexemes and morphemes that appear over and over again in many place names throughout the Republic of Ireland and Northern Ireland.
Referring to The Placenames Database of Ireland, we have accumulated statistical data concerning Irish place names in various parts of Ireland. We have tried to make inferences based of the investigated data, i.e. to interpret them and provide reasons. The quantitative analysis therefore helped us to make a claim that Irish place names in Gaeltacht substantially outnumber toponyms of Irish origin in other parts of the island.
In accordance with the next objective, we have analyzed the use of toponyms of Celtic origin in the places where the Irish diaspora is present, namely in North America, Canada, Australia and the UK. The majority of place names in these places trace their origin in Irish surnames as well as in the lexemes denoting geographical landscape. Our fi nding was that they are always anglicized equivalents of the Irish words.
Our further objective was to draw a typology of toponyms and analyze cultural components in the meaning of linguistic units. Thus, we have grouped them into the following thematic groups: 1) place names containing linguistic elements associated with geographical features; 2) place names containing surnames; 3) place names containing linguistic elements associated with mythological fi gures, legendary heroes and deities; 4) place names containing names of Christian saints and martyrs; 5) place names containing linguistic elements associated with man-made objects.
In addition, cultural components in the meaning of linguistic units denoting geographical objects, both natural and man-made, were analyzed. The obtained fi ndings convincingly demonstrate that substantial number of toponyms used today carry information about the Celtic cultural and national heritage, proving that it still thrives and that the Irish are conscious of their legacy.
Implications for Further Research. Taking into account the complexity of the analyzed issues, our article falls short of addressing the functions of place names bearing Celtic language components, which can be addressed in our further research. Additionally, we wish to pursue the comparative study of the Irish, Scottish and Welsh place names, which remain underinvestigated.
