Irish dialects today

The term for an Irish-speaking area is Gaeltacht ‘Irish region’ (Ó Riagáin 2007: 224ff.). In present-day Ireland a distinction is made between two types of Gaeltacht, depending on the numbers of Irish-speakers living there: (1) Fíor-Ghaeltacht, lit. ‘true Irish-area’ refers to those areas with a high-percentage of speakers (though the threshold for this has not been officially defined) and (2) Breac-Ghaeltacht, lit. ‘part Irish-area’ which has considerably fewer Irish speakers. Occasionally, the English-speaking areas are referred to collectively as Galltacht ‘region of the non-Irish’, the stem Gall- meaning ‘foreign(er)’.

The standard dialect survey of Irish is Heinrich Wagner’s comprehensive atlas (see Wagner 1958-64). But even when this was being compiled in the mid twentieth century the speakers were older males whose Irish was frequently moribund. The situation today is that large tracts of both halves of Ireland have no historically continuous Irish-speaking areas any more. There are no such areas in Northern Ireland or in Leinster. In Munster there are remnants in Ring in Co. Waterford and in Muskerry in Co. Cork. along with a more robust community at the end of the Dingle peninsula in Co. Kerry. The community on Clear Island off the south-west coast of Cork contains virtually no native speakers, see Ó Buachalla 2003 for a treatment of this dialect.

Irish in Mayo receded dramatically in the second half of the twentieth century, so that the studies of de Búrca (1958) and that of Mhac an Fhailigh (1968) are now of largely historical interest. The areas in coastal Co. Galway and on the two minor Aran Islands, as well as that on Tory Island in Donegal and the mainland opposite it, represent the most vibrant communities today.

Dialects and the teaching of Irish

If there is no standard pronunciation of Irish how and what do students of the language learn? The answer is quite simple: for grammar and vocabulary students learn from textbooks and dictionaries. They are taught pronunciation from their teachers. These will have a single pronunciation based on the dialect which they in turn followed when they were learning the language. In general one can say that people from the south follow a southern pronunciation and those from the north a northern pronunciation. Those from the centre or east of the country follow a western or southern pronunciation but rarely if ever a northern one.

Put in terms of colleges and universities this rule of thumb works out as follows. At the universities in Cork and Limerick a southern pronunciation is the rule, at the university in Galway a western pronunciation is usual. At northern universities, i.e. at Queen’s University in Belfast and at the various campi of the University of Ulster (in Belfast, Coleraine and Derry) a northern pronunciation dominates. In Dublin universities (University College Dublin, Trinity College Dublin, Dublin City University) either a western or a southern pronunciation is common as these institutions tend in the main to service students from the Republic of Ireland, south of Ulster. It is true that Donegal is in the republic, but in language it receives its greatest support from universities in Northern Ireland. Similar to the universities, the institutes of technology tend to follow the accent of the region in they are located, assuming that they have academic programmes for Irish.

An additional factor is the question of where students of Irish go to practice the spoken language. There are three choices here: the summer schools and colleges in the Kerry, Connemara or Donegal Gaeltacht. For students, spending time in a Gaeltacht will strengthen their pronunciation for that region. And of course students are encouraged by their college teachers to decide on one dialect and keep to this. For students of Irish it is important to grasp what features are typical of what dialect region.

In the following sections, the main phonological differences between the dialects of Irish, as recorded in the available literature, are given in summary form. The references are to individual studies. More general literature is also available, from the mid-19th century grammar by O’Donovan (1845) to the influential study by O’Rahilly (1932) to later works like Ó Cuív (1951) and Ó Siadhail (1989). The main differences between the dialects are to be found among vowels which is why it is so difficult to arrive at a common pronunciation for all three main dialect areas (but see Ó Baoill 1986 and Ó Baoill (ed.) 1990). Most general works on Irish often fudge the issue by not giving pronunciations (the official standard does not either). One or two are based on a particular dialect, such as Ó Siadhail (1980) which relies on western Irish pronunciation.

For more information on different pronunciations and for active maps, consult the module on dialect variation.

Southern Irish

This refers to a few areas in the southern province of Munster. The main one is the end of the Dingle Peninsula (Irish: Corca Dhuibhne). The others comprise a small area on the Iveragh Peninsula, an inland area in Co. Cork, the island of Cape Clear as well as the area of Ring in West Waterford (see map above).

For all dialects areas, the reflexes of historical vowels before former geminate sonorants play an important role in differentiation. In Southern Irish the following realisations are found: /i/ > /ai/ cinn ‘heads’, /o/ > /au/ trom ‘heavy’, /a/ > /au/ crann ‘tree’. The following features are also important in delimiting southern Irish from forms in the west and north.

The realisation of <ao> This is pronounced /e:/, e.g. glaoch /gle:x/ ‘call’. See O’Rahilly (1932: 27-38) for an overview in all the dialects including Scottish Gaelic.

Sonorants A two-way distinction is found for N and L. Velar stops are retained in post-nasal position, i.e. teanga is [tjæŋgə] ‘tongue’.

/v/ before a back or low vowel is realised as [v].

The realisation of coronal stops These are realised with very slight palatalisation. The non-palatal stops /t/ and /d/ are alveolar.

Word stress Long vowels in non-initial syllables attract stress, e.g. cailín /kaˡlji:nj/ ‘girl’. This may be the result of Anglo-Norman influence (in the south-east) after the 12th century as older authors like O’Rahilly seem to think (1932: 86-98) and certainly applied to many French loanwords, e.g. buidéal /bəˡdje:l/ ‘bottle’. See Hickey (1997) for further discussion.


Déise Irish, Ring (South Co. Waterford), Henebry (1898), Breatnach (1947), Sheehan (1944).
West Muskerry (West Co. Cork), Ó Cuív (1944).
Dunquin (Dingle Peninsula, Co. Kerry), Sjoestedt-Jonval (1931, 1938), Ó Sé (1995, 2000).

Western Irish

This refers to forms of Irish spoken west of Galway and on the Aran Islands. Irish is still a daily language for most of the population in Cois Fhairrge (immediately west of Galway city) and the areas around An Cheathrú Rua (Carraroe), Ros Muc, Cill Chiaráin, Carna (on the peninsula known in Irish as Iorras Aithneach) further along the coast. This is encompasses the area known as Ceanter na nOileán ‘district of the islands’, especially because the largest of these, Leitir Móir ‘Lettermore’ is a strong Irish-speaking area. Western Irish also includes the two smaller Aran Islands (in Galway Bay), Inis Meáin and Inis Oírr as well as the main island Inis Móir, especially outside the main town of Cill Rónáin. Western Irish would also include the area of Tuar Mhic Éadaigh (Tourmakeady) in south Mayo.

Reflexes of historical vowels before former geminate sonorants: /i/ > /i:/ cinn, ‘heads’, /o/ > /u:/ trom ‘heavy’, /a/ > /a:/ [ɑ:] crann ‘tree’.

The realisation of <ao> This is generally pronounced /i:/, e.g. glaoch /gli:x/ ‘call’.

Sonorants A three-way distinction is found for N and L, i.e. /nˠ – n – nj/ and /lˠ – l – lj/. Velar stops are not retained in post-nasal position in Cois Fhairrge, i.e. teanga is [tjæŋə] ‘tongue’, but these are found in this position further to the west.

/v/ before a back or low vowel is realised as [w].

The realisation of coronal stops These are realised in western Irish as true palatals without noticeable affrication. The stops /t/ and /d/ are dental.

Word stress Initial stress applies to virtually all words with the exception of one or two loanwords such as tobac /təˡba:k/ ‘tobacco’.


Cois Fhairrge (Mid-West Co. Galway), de Bhaldraithe (1945, 1953).
Iorras Aithneach (West Co. Galway), Ó Curnáin (2007).
Inishmaan (middle Aran Island, Galway Bay), Finck (1899).
Tourmakeady (South Co. Mayo), de Búrca (1958).
Erris (North-West Co. Mayo), Mhac an Fhailigh (1968).
Achill (West Co. Mayo), Stockman 1974.

Remnants of Irish in Co. Clare (transitional between the west and south) are described in Holmer (1962-5).

Northern Irish (Ulster Irish)

Up to the early 20th century there were still remnants of Ulster Irish spoken in central Tyrone (in the Sperrin Mountains), in the Glens of Antrim and on Rathlin Island (both in the extreme north-east of Ireland). Somewhat earlier still Irish could be found in south Armagh and on the Cooley Peninsula in Co. Louth.

Today the Irish language is spoken in Ulster in two main areas on the coast of Co. Donegal. The first is in the south-west of this country (Wagner 1979 [1959]) and the second and larger area is in the north-west, particularly the region around Gaoth Dobhair. Irish is also spoken on Tory Island off the north-west coast. The Irish term for the Donegal Gaeltacht is Tír Chonaill (‘country of Connell’). The region in the vicinity of Gaoth Dobhair is often referred to as Cloich Cheannfhaola (‘Kineely’s stone’).

Reflexes of historical vowels before former geminate sonorants: /i/ > /i/ cinn ‘heads’, /o/ > /ɔ/ trom ‘heavy’, /a/ > /a/ crann ‘tree’.

The realisation of <ao> This is pronounced as a retracted high front vowel: /ɨ:/, e.g. glaoch /glɨ:x/ ‘call’. The degree of retraction for this vowel is greatest in the north of Donegal.

Other vowels There is a general fronting of vowels in northern Irish. The /u:/ is pronounced as a high rounded vowel, much as in the rest of Ulster (an areal feature covering both Irish and English), e.g. cúl [kʉ:l] ‘rear’. The long low vowels, pronounced [ɑ:] in western Irish, is often fronted to a value nearer [æ:] or [ɛ:], e.g. [tæ:, tɛ:] ‘(it) is’. A lowered and retracted variant of /e:/ is found as the reflex of /a/ and a velar fricative, e.g. slaghdán [slˠɛdˠənˠ] ‘cold (illness)’. The mid back vowel /o:/ is also lowered, e.g. pósta [pɑ:stə] ‘married’.

Sonorants A three-way distinction is found for N and L, i.e. /nˠ – n – nj/ and /lˠ – l – lj/. Velar stops are variably retained in post-nasal position, i.e. teanga is [tjæŋ(g)ə] or [tjæŋ(g)i] ‘tongue’.

/v/ before a back or low vowel is realised as [w].

The realisation of coronal stops These are realised in northern Irish as palatals with audible affrication. The stops /t/ and /d/ are dental.

Word stress Stress is on the first syllable though there is considerable shortening of post-initial long vowels (as opposed to western Irish), e.g. sceireog ‘fib, lie’ /ˡsjkjɛrəg/.

The Mayo dialects in the north-west of this county, which are spoken by very small numbers today, are not simply transitional between the central western and the northern dialects. They show a large number of Ulster features due the resettlement of people from Ulster in north-west Mayo in the 17th century. The Irish of this region has been studied, in particular in Erris (North-West Co. Mayo) by Mhac an Fhailigh (1968) and in Achill (West Co. Mayo) by Stockman (1974). For East Co. Mayo, see Ó Catháin (forthcoming). See Ó Dochartaigh (1987) for a general overview.

The Doegen Tapes

There is a collection of tape recordings made of native speakers by the German scholar Dr. Wilhelm Doegen between 1928 and 1931. The tapes in questions were digitised in a Royal Irish Academy-funded project. They provide invaluable insights into the nature of Irish about a century ago and help to fill in certain gaps of our knowledge of areas which no longer contain any native speakers, e.g. Co. Clare, an important transition area between Munster and Connacht.

More information on the tapes from Ulster is available at (provided by the Scottish Gaelic College, Sabhal Mòr Ostaig.

Dialects of English in Ireland

The following map shows the dialect regions for varieties of English in Ireland. There is a certain correlation with Irish inasmuch as Ulster is a separate area here as well. The large west and south-west English dialect area corresponds to the region which contains western and southern Irish. These varieties previously filled the entire region. Historically, it is the presence of Irish in this region which is responsible for the linguistic characteristics of English there: speakers who shifted from Irish to English transferred features of their first language to the new target language and many of these became established features of English in the west and south-west of Ireland.
