during articulation). The contrast between broad and slender consonants is crucial in Irish, because the meaning of a word can change if a broad consonant is substituted for a slender consonant or vice versa. For example, the only difference in pronunciation between the words ('cow') and ('alive') is that is pronounced with broad , while is pronounced with slender . The contrast between broad and slender consonants plays a critical role not only in distinguishing the individual consonants themselves, but also in the pronunciation of the surrounding

The precise phonetic definition of these terms is somewhat vague, but the coronal fortis sounds (spelled ) were probably longer in duration and may have had a larger area of contact between the tongue and the roof of the mouth than the lenis sounds. Fortis was probably a normal , while lenis was a nasalized semivowel , perhaps tending towards a nasalized fricative or when palatalized. By convention, the fortis coronals are transcribed with small capital letters or

phonemes . Fortis and lenis sonorants contrasted with each other between vowels and word-finally after vowels in Old Irish, e.g. ('he shears') vs. ('he may carry'); ('hazel') vs. ('sin'); ('stake') vs. ('sound'). Word-initially, only the fortis sounds were found, but they became lenis in environments where
morphosyntactically triggered lenition was found: ('mystery') vs. ('his mystery'), ('provision') vs. ('his provision').
In the modern language, the four rhotics have been reduced to two in all dialects, having merged as . For the laterals and nasals, some dialects have kept all four distinct, while others have reduced them to three or two distinct phonemes, as summarized in the following table.
As for fortis and lenis , in time the lenis version (nasalized semivowel or labial fricative) came to be pronounced as a regular semivowel or fricative along with nasalization of the preceding vowel. The later loss of between vowels has resulted in phonemically nasalized vowels in some modern dialects (see
below), but these are not robustly maintained in any dialect; the strong tendency is to eliminate the nasalization entirely. The original nasalized semivowel is still reflected as in the spelling, however.

The near-close vowels and show a similar pattern. is realized between slender consonants as a front , e.g. ('house'

s varies according to the quality of the surrounding consonants; there is a significant difference between Munster dialects and Connacht dialects as well. In Munster, long and short have approximately the same range of realization: both vowels are relatively back in contact with broad consonants and relatively front in contact with slender consonants. Specifically, long in word-initial position and after broad consonants is a back , e.g. ('place'), ('beach'). Between a slender and a broad consonant, it is a retracted front , e.g. ('will cut'), while between two slender consonants it is a fully front , e.g. ('John'
voc.). In Dingle, the back allophone is rounded to after broad labials, e.g. ('white'), while in
Ring, County Waterford, rounded is the usual realization of in all contexts except between slender consonants, where it is a centralized . Short between two slender consonants is a front , as in ('short'). Between a broad and a slender consonant, it is in most cases a retracted , e.g. ('man'), and ('worn'), but after broad labials and it is a centralized front , e.g. ('town'), ('injure'). When it is adjacent only to broad consonants, it is a centralized back , e.g. ('son'), ('say').

In Connacht varieties, the allophones of short are consistently further front than the allophones of long . In Erris, for example, short ranges from a
near-open front vowel before slender consonants (e.g. 'earwax') to an open after slender consonants (e.g. 'bright') to a centralized back between broad consonants (e.g. 'horse'). Long , on the other hand, ranges from a back between broad consonants (e.g. 'boat') to an advanced back before slender consonants (e.g. 'to get') to a centralized back after slender consonants (e.g. 'fine'). In
Toormakeady, the back allophone is rounded to after broad labials, e.g. ('white'). In Connemara, the allophones of are lengthened in duration, so that only vowel quality distinguishes the allophones of from those of .

However, the contrast is not robust in any dialect; most published descriptions say that contrastively nasal vowels are present in the speech of only some (usually older) speakers. Potential minimal pairs include those shown in the table below.
In addition, where a vowel is nasalized because it is adjacent to a nasal consonant, it often retains its nasalization in related forms where the consonant is no longer nasal. For example, the nasal of ('mother') is replaced by nonnasal in the phrase ('his mother'), but the vowel remains nasalized. Similarly, in ('snow') the vowel after the is nasalized, while in ('the snow' gen.), the is replaced by in some northern dialects, but the nasalized vowel remains.

Word-initial consonant clusters

Irish words can begin with clusters of two or three consonants. In general, all the consonants in a cluster agree in their quality, i.e. either all are broad or all are slender. Two-consonant clusters consist of an
obstruent consonant followed by a
liquid
Liquid is a state of matter with a definite volume but no fixed shape. Liquids adapt to the shape of their container and are nearly incompressible, maintaining their volume even under pressure. The density of a liquid is usually close to th ...

(however, labial obstruents may not be followed by a nasal); examples (from ) include ('milking'), ('fine'), ('button'), ('law'), ('usual'), ('idiot'), ('slice'), ('snow'), ('poker'), and ('long for'). In addition, and may be followed by a voiceless stop, as in ('purse') and ('story'). Further, the cluster occurs in the word ('women') and a few forms related to it. Three-consonant clusters consist of or plus a voiceless stop plus a liquid. Examples include ('rumpus'), ('scream'), ('flash'), ('fun'), and ('streak').
One exception to quality agreement is that broad is found before slender labials (and for some speakers in Connemara and Dingle before as well). Examples include: ('berries'), ('scythe'), ('dependent'), ('inspire'), and ('story').
In the environment of an initial
consonant mutation
Consonant mutation is change in a consonant in a word according to its morphological or syntactic environment.
Mutation occurs in languages around the world. A prototypical example of consonant mutation is the initial consonant mutation of al ...
, there is a much wider range of possible onset clusters; for example, in a lenition environment the following occur: ('tasted'), ('broke'), ('practiced'), ('bent'), ('stuck'), ('acted'), ('slipped'), ('swam'), ('reached'). In an eclipsis environment, the following are found: ('flower'), ('years'), ('you would break'), ('warp'), ('bridge'), ('ladder'), ('you would dress'), ('you would leave'), ('you would act').
In Donegal, Mayo, and Connemara dialects (but not usually on the Aran Islands), the coronal nasals can follow only respectively in a word-initial cluster. After other consonants, they are replaced by : ('hill'), ('women'), ('liking'), ('long for').
Under lenition, become as expected in these dialects, but
after the definite article ''an'' they become : ('snow'), ('snow'
enited form, ('the snow' gen.).
Post-vocalic consonant clusters and epenthesis

Like word-initial consonant clusters, post-vocalic consonant clusters usually agree in broad or slender quality. The only exception here is that broad , not slender , appears before the slender coronals : ('two people'), ('trade'), ('doors'), ('handle'), ('advice').
A cluster of , , or followed by a labial or dorsal consonant (except the voiceless stops , ) is broken up by an
epenthetic vowel : ('abrupt'), ('blue'), ('mistake'), ('certain'), ('service'), ('anger'), ('dark'), ('bold'), ('dove'), ('pleasant'), ('sparrow'), ('venom'), , (a name for Ireland), ('name'), ('mind'), ('animal').
There is no epenthesis, however, if the vowel preceding the cluster is long or a diphthong: ('wrinkle'), ('term'), ('insight'), ('duty'). There is also no epenthesis into words that are at least three syllables long: ('firmament'), ('throat'), ('dandelion'), ('Carmelite').
Phonological processes
Vowel-initial words
Vowel-initial words in Irish exhibit behaviour that has led linguists to suggest that the vowel sound they begin with on the surface is not actually the first sound in the word at a more abstract level. Specifically, when a clitic ending in a consonant precedes a word beginning with the vowel, the consonant of the clitic surfaces as either broad or slender, depending on the specific word in question. For example, the of the
definite article
In grammar, an article is any member of a class of dedicated words that are used with noun phrases to mark the identifiability of the referents of the noun phrases. The category of articles constitutes a part of speech.
In English, both "the" ...
('the') is slender before the word ('wonder') but broad before the word ('age'): ('the wonder' gen.) vs. ('the age').
One analysis of these facts is that vowel-initial words actually begin, at an abstract level of representation, with a kind of "empty" consonant that consists of nothing except the information "broad" or "slender". Another analysis is that vowel-initial words, again at an abstract level, all begin with one of two

s, one triggering palatalization and the other triggering velarization of a preceding consonant.
Lengthening before fortis sonorants
Where reflexes of the Old Irish
fortis sonorants appear in syllable-final position (in some cases, only in word-final position), they trigger a lengthening or diphthongization of the preceding vowel in most dialects of Irish. The details vary from dialect to dialect.
In Donegal and Mayo, lengthening is found only before , before (except when a vowel follows), and in a few words also before word-final , e.g. ('top'), ('tall'), ('inch'), ('spinning wheel'), ('yonder').
In Connemara, the Aran Islands, and Munster, lengthening is found generally not only in the environments listed above, but also before (unless a vowel follows) and before word-final . For example, the word ('hole') is pronounced in all of these regions, while ('grip') is pronounced in Connemara and Aran and in Munster.
Because vowels behave differently before broad sonorants than before slender ones in many cases, and because there is generally no lengthening (except by

singular of the same word) is pronounced with a long vowel, while (the plural, meaning 'heads') is pronounced with a short vowel.
This lengthening has received a number of different explanations within the context of theoretical phonology. All accounts agree that some property of the fortis sonorant is being transferred to the preceding vowel, but the details about what property that is vary from researcher to researcher. argue that the fortis sonorant is
tense (a term only vaguely defined phonetically) and that this tenseness is transferred to the vowel, where it is realized phonetically as vowel length and/or diphthongization. argues that the triggering consonant is underlyingly associated with a unit of
syllable weight

called a
''mora''; this mora then shifts to the vowel, creating a long vowel or a diphthong. expands on that analysis to argue that the fortis sonorants have an
advanced tongue root (that is, the bottom of the tongue is pushed upward during articulation of the consonant) and that diphthongization is an
articulatory effect of this tongue movement.
Devoicing

verbal adjectives (where is spelled ). For example, the verb ('sweep') ends in the voiced consonant , but its future tense ('will sweep') and verbal adjective ('swept') have the voiceless consonant .

effects, i.e. phonological changes across word boundaries, particularly in rapid speech. The most common type of sandhi in Irish is
assimilation, which means that a sound changes its pronunciation in order to become more similar to an adjacent sound. One type of assimilation in Irish is found when a coronal consonant () changes from being broad to being slender before a word that begins with a slender coronal consonant and vice versa. For example, ('deceive') ends with a broad , but in the phrase ('it deceived me'), the has become slender because the following word, , starts with a slender coronal consonant.

of a following consonant, becoming labial before a labial consonant, palatal before a palatal consonant, and velar before a velar consonant. For example, of ('one') becomes in ('a lame one') and in ('a scabbed one'). A voiced consonant at the end of a word may devoice when the next word begins with a voiceless consonant, as in ('he bent'), where of ('bent') became before the voiceless of .
Stress
General facts of stress placement
In Irish, words normally have only one
stressed syllable (ˈ◌), namely the first syllable of the word, e.g. ('left'
erb and ('dishonor'). However, certain words, especially
adverb An adverb is a word or an expression that generally modifies a verb, an adjective, another adverb, a determiner, a clause, a preposition, or a sentence. Adverbs typically express manner, place, time, frequency, degree, or level of certainty by ...
s and
loanword
A loanword (also a loan word, loan-word) is a word at least partly assimilated from one language (the donor language) into another language (the recipient or target language), through the process of borrowing. Borrowing is a metaphorical term t ...
s, have stress on a noninitial syllable, e.g. ('only'), ('tobacco').
In most
compound words, primary stress falls on the first member and a
secondary stress (ˌ◌) falls on the second member, e.g. ('spent bog'). Some compounds, however, have primary stress on both the first and the second member, e.g. ('a terrible lie').
In Munster, stress is attracted to a long vowel or diphthong in the second or third syllable of a word, e.g. ('girl'), ('request'). In the now-extinct accent of East Mayo, stress was attracted to a long vowel or diphthong in the same way as in Munster; in addition, stress was attracted to a short vowel before word-final when that word was also final in its utterance. For example, ('horse') was pronounced in isolation or as the last word of a sentence, but as in the middle of a sentence.
In Munster, stress is attracted to in the second syllable of a word if it is followed by , ''provided'' the first syllable (and third syllable, if there is one) contains a short vowel. Examples include ('lame') and ('chips'). However, if the first or third syllable contains a long vowel or diphthong, stress is attracted to that syllable instead, and the before is reduced to as normal, e.g. ('listen'), ('wether').
The nature of unstressed vowels
In general, short vowels are all reduced to
schwa () in unstressed syllables, but there are exceptions. In Munster, if the third syllable of a word is stressed and the preceding two syllables are short, the first of the two unstressed syllables is ''not'' reduced to ; instead it receives a secondary stress, e.g. ('scythe-man'). Also in Munster, an unstressed short vowel is not reduced to if the following syllable contains a stressed or , e.g. ('art'), ('gather'). In Ulster, long vowels in unstressed syllables are shortened but are not reduced to , e.g. ('girl'), ('gallon'). In Ulster, unstressed before is not reduced to
schwa, e.g. ('cattle').

; both Scottish Gaelic and Manx have lost the distinction in labial consonants. The change of etc. to etc. is found in Manx and most dialects of Scottish Gaelic. Evidence from written manuscripts suggests it had begun in Scottish Gaelic as early as the 16th century and was well established in both Scottish Gaelic and Manx by the late 17th to early 18th century. Lengthening or diphthongization of vowels before fortis sonorants is also found in both languages. The stress pattern of Scottish Gaelic is the same as that in Connacht and Ulster Irish, while in Manx, stress is attracted to long vowels and diphthongs in noninitial syllables, but under more restricted conditions than in Munster.
Manx and many dialects of Scottish Gaelic share with Ulster Irish the property of not reducing unstressed to before .
