Irish phonology

From Free net encyclopedia

The phonology of the Irish language varies from dialect to dialect. The processes discussed here reflect a somewhat idealized version of "school Irish" that tends to be used by teachers outside of the Gaeltacht areas.

The phonemes of Irish

Consonants

The consonant inventory of Irish is set out – using the International Phonetic Alphabet – in the table below.

The distinction between velarized "broad" consonants and palatalized "slender" consonants is phonemic in Irish. Template:IPA is the only consonant phoneme without a broad/slender distinction; other pairs not immediately obvious in the table above are:

Broad (velarized) consonants have a noticeable velar offglide before front vowels, thus Template:IPA 'thatch' and Template:IPA 'way, manner' are pronounced Template:IPA and Template:IPA. This velar offglide is labialized after labial consonants, so Template:IPA 'yellow' is pronounced Template:IPA. The realization of the slender consonants varies somewhat from dialect to dialect; for example Template:IPA is an affricate Template:IPA in Ulster, a palatalized Template:IPA in Connacht, and an apical postalveolar Template:IPA in Munster.

Template:IPA and Template:IPA are not separate phonemes. In Munster only Template:IPA is found, and in Ulster only Template:IPA. In Connacht Template:IPA is found in syllable onsets and Template:IPA in syllable codas. In older varieties of Irish, Template:IPA and Template:IPA were bilabial fricatives but today because of English influence most people make them labiodental.

The broad coronals Template:IPA have a dental articulation as in Romance languages, and as in the Hiberno-English pronunciation of the English th sounds of thin and this.

Template:IPA is not strictly a postalveolar but rather an alveopalatal fricative Template:IPA like Polish si or Mandarin x. Nevertheless the more familiar symbol Template:IPA is usually used.

Template:IPA is a short palatalized flap similar to the tt in American English pretty.

Slender Template:IPA is a voiceless (post)palatal fricative Template:IPA like the German ich-Laut. The symbol Template:IPA is used to emphasize its relationship with the stop Template:IPA in the system of initial mutations.

Template:IPA is a palatal glide Template:IPA (like English y in yellow) before vowels; before consonants and at the ends of syllables it is a voiced (post)palatal fricative Template:IPA.

Usually all the consonants in a cluster have the same broad/slender quality, for example freagra Template:IPA 'answer'. Cf. also seachain Template:IPA 'avoid (imperative)' with slender Template:IPA but seachnaím Template:IPA 'I avoid' with broad Template:IPA, because it is next to broad Template:IPA. But there are some systematic exceptions:

As in English, voiceless stops are aspirated at the start of a word, and unaspirated after Template:IPA. Also, as in English, voiced stops may not be fully voiced but are never aspirated.

Vowels

The vowels (monophthongs and diphthongs) of Irish are given in the tables below.

Monophthongs Short Long
Close ("high") Template:IPA Template:IPA Template:IPA
Mid Template:IPA Template:IPA Template:IPA
Open ("low") Template:IPA Template:IPA
Diphthongs Closer component

is back
Closing Template:IPA Template:IPA
Centering Template:IPA Template:IPA

The backness contrast in short vowels is not phonemic.

Of the high phoneme:

  • The allophone Template:IPA appears:
    • before slender consonants (written i, ui)
    • between a slender consonant and a broad coronal or Template:IPA (written io)
  • The allophone Template:IPA appears:
    • between broad consonants (written u; also in uicht, uirs, uirt(h) where the first consonant of the cluster is broad)
    • between a slender consonant and a broad labial or velar (written io, iu)

Of the mid phoneme:

  • The allophone [o] appears:
    • between broad consonants (written o; also in oicht, oirs, oirt(h) where the first consonant of the cluster is broad)
    • before Template:IPA (written ois)
    • rarely between a slender consonant and a broad velar, for example deoch Template:IPA 'a drink', beag Template:IPA 'small'

The backness distinction is phonemic among long vowels, and all long vowels and diphthongs can stand next to both qualities of consonant. Exception: Template:IPA stands only word-initially or after a slender consonant, while Template:IPA stands only word-initially or after a broad consonant. Thus minimal pairs for these two diphthongs can be found only word-initially, for example iallach Template:IPA 'constraint' vs. ualach Template:IPA 'burden'.

The mid vowels are raised to high vowels before a nasal and orthographic mh Template:IPA.

Short vowels are reduced to schwa Template:IPA in unstressed syllables.

Long Template:IPA is optionally diphthongized to Template:IPA before broad Template:IPA, Template:IPA, for example fíor Template:IPA ~ Template:IPA 'true', eolaíocht Template:IPA ~ Template:IPA 'science'.

Template:IPA is a slightly rounded lax mid central vowel; in effect, it is the vowel of the English word cup with slightly rounded lips. (This is in fact a common Hiberno-English pronunciation of that vowel.)

The back long vowels Template:IPA tend to be diphthongized before slender consonants, for example Máire Template:IPA 'Mary', go fóill Template:IPA 'still', cúig Template:IPA 'five'.

Vowel-initial words

Vowel-initial words in Irish exhibit behavior that has led linguists to suggest they begin with a latent onset that, like consonants, can be either velarized (broad) or palatalized (slender).

For example, when the vowel-initial words arcán Template:IPA 'piglet' and uimhríonn Template:IPA 'numbers' (present-tense verb) are preceded by a proclitic ending in a consonant, that consonant is broad: m'arcán Template:IPA 'my piglet'; d'uimhrigh Template:IPA 'numbered'.

But when the words earc Template:IPA 'lizard' and imíonn Template:IPA 'leaves' (present-tense verb) are preceded by the same proclitics, the consonant is slender: m'earc Template:IPA 'my lizard'; d'imigh Template:IPA 'left'.

This difference is not predictable, it is a lexical property of each individual vowel-initial word. Thus some linguists have argued that roots like arcán and uimhr- actually begin with a consonant containing no features except that of being velarized, and roots like earc and im- with a consonant containing no features except that of being palatalized.

When Template:IPA is lenited to zero, its quality remains if a consonant-final proclitic takes its place, as in:

fargán Template:IPA 'ledge' m'fhargán Template:IPA 'my ledge'
fearg Template:IPA 'anger' m'fhearg Template:IPA 'my anger'
filleann Template:IPA 'returns' d'fhill Template:IPA 'returned'
fuilíonn Template:IPA 'bleeds' d'fhuiligh Template:IPA 'bled'

Stress in Irish

An Irish word normally has only one stressed syllable, namely the first one:

Certain adverbs and loanwords have stress on a noninitial syllable:

In compounds more than one syllable is stressed:

Most compounds are like Template:IPA meánaois, the primary stress falls on the first member and the secondary stress on the second:

The prefixes Template:IPA do- 'bad, hard to ..., un-X-able', Template:IPA so- 'good, easy to...' and Template:IPA in- '-able' take the secondary accent; the primary accent falls on the second member:

Some compounds have primary stress on both the first and the second member:
