Irish, like all modern Celtic languages, is characterized by its initial consonant mutations.[1] These mutations affect the initial consonant of a word under specific morphological and syntactic conditions. The mutations are an important tool in understanding the relationship between two words and can differentiate various meanings.
Irish, like Manx and colloquial Scottish Gaelic, uses two mutations on consonants: lenition (Irish: séimhiú [ˈʃeː.vʲuː]) and eclipsis (urú [ˈʊ.ɾˠuː]) (the alternative names, aspiration for lenition and nasalisation for eclipsis, are also used, but those terms are misleading).
Originally these mutations were phonologically governed external sandhi effects: lenition was caused by a consonant being between two vowels, and eclipsis when a nasal preceded an obstruent, including at the beginning of a word.
There are also two mutations, t-prothesis and h-prothesis, found on vowel-initial words.
See Irish phonology for a discussion of the symbols used on this page.
Lenition (séimhiú)[]
Effects of séimhiú[]
- A stop becomes a fricative. Voicing is retained, as is place of articulation except with the coronals.
- /pˠ/ → /fˠ/
- /pʲ/ → /fʲ/
- /t̪ˠ/ → /hʲ/
- /tʲ/ → /h/
- /k/ → /x/
- /c/ → /ç/
- /bˠ/ → /w/, /v/
- /bʲ/ → /vʲ/
- /d̪ˠ/ → /ɣ/
- /dʲ/ → /j/
- /ɡ/ → /ɣ/
- /ɟ/ → /j/
- /mˠ/ becomes /w/ or /v/; /mʲ/ becomes /vʲ/.
- /sˠ/ and /ʃ/ become /h/; but /sˠp(ʲ)/, /sˠm(ʲ)/, /sˠt̪ˠ/, /ʃtʲ/, /sˠk/, and /ʃc/ do not mutate.
- /fˠ/ and /fʲ/ are deleted.
Séimhiú is symbolized in the orthography by an h following the consonant in question or, in some older typefaces and texts, by a dot (◌̇) above the letter that has undergone lenition.
Normal | Séimhiú | Gloss |
---|---|---|
peann /pʲaːn̪ˠ/ | pheann /fʲaːn̪ˠ/ | "pen" |
teach /tʲax/ | theach /hax/ | "house" |
ceann /caːn̪ˠ/ | cheann /çaːn̪ˠ/ | "head" |
bean /bʲan̪ˠ/ | bhean /vʲan̪ˠ/ | "woman" |
droim /d̪ˠɾˠiːmʲ/ | dhroim /ɣɾˠiːmʲ/ | "back" |
glúin /ɡɫ̪uːnʲ/ | ghlúin /ɣɫ̪uːnʲ/ | "knee" |
máthair /mˠaːhəɾʲ/ | mháthair /waːhəɾʲ/, /vaːhəɾʲ/ | "mother" |
súil /sˠuːlʲ/ | shúil /huːlʲ/ | "eye" |
freagra /fʲɾʲaɡɾˠə/ | fhreagra /ɾʲaɡɾˠə/ | "answer" |
The other consonants do not change under lenition.
Environments of séimhiú[]
After proclitics[]
- After the definite article
The definite article triggers lenition of:
- a feminine noun in the nominative singular
- an bhean "the woman"
- a masculine noun in the genitive singular
- an fhir "of the man" e.g. carr an fhir, the man's car (car of the man)
- a noun in the dative singular, when the article follows one of the prepositions de "from", do "to" or i "in"
- do + an = don: don fhear "to the man"
- de + an = den: den bhean "from the woman"
- i + an = sa(n): sa chrann "in the tree"; san fhómhar "in the autumn"
- /d̪ˠ, dʲ/ and /t̪ˠ, tʲ/ are never lenited after the article:
- an deoch "the drink", although deoch is feminine nominative singular
- an tí "of the house", although tí is masculine genitive singular
- Where an /sˠ, ʃ/ would be lenited after the article, it becomes /t̪ˠ, tʲ/ (rather than /h/), written ts:
- an tsúil /ən̪ˠ t̪ˠuːlʲ/ "the eye" (fem. nom. sg.)
- an tsaoil /ən̪ˠ t̪ˠiːlʲ/ "of the world" (masc. gen. sg.)
- After the vocative particle a
- a Bhríd "Bríd!"
- a Sheáin "Seán!"
- a chairde "my friends!"
- After possessive pronouns
The possessive pronouns that trigger lenition are mo "my", do "your (sg.)", a "his"
- mo mhac "my son"
- do theach "your house"
- a pheann "his pen"
- After certain prepositions
- de chrann "out of a tree"
- faoi chrann "under a tree"
- mar dhuine "as a person"
- ó Chorcaigh "from Cork"
- roimh mhaidin "before morning"
- trí shioc agus shneachta "through frost and snow"
- um Cháisc "at Easter"
- idir fhir agus mhná "both men and women"
- ar bhord "on a table"
- After the preterite/conditional of the copula
- Ba dhuine mór é. "He was a big person."
- Ba dheas uait é. "That was nice of you."
- After the preterite preverbal particles
- Níor mhúinteoir é. "He was not a teacher."
- Níor thug mé "I didn't give"
- Ar shagart é? "Was he a priest?"
- Ar tháinig sé? "Did he come?"
- After certain preverbal particles
- ní thuigim "I don't understand"
- má thagann sé "if he comes"
- an fear a thabharfaidh dom é "the man who will give it to me"
- A verb in the preterite, imperfect or conditional
These were originally preceded by the particle do and often still are in Munster.
- bhris mé "I broke"
- bhrisinn "I used to break"
- bhrisfinn "I would break"

Eclipsis (urú)[]
Effects of urú[]
The following tables show how eclipsis affects the start of words. Eclipsis is symbolised in the orthography by adding a letter—or occasionally two letters—to the start of the word. If the word is to be capitalised, the original first letter is capitalised, not the letter or letters added for eclipsis. An example is the "F" in Ireland's national anthem, Amhrán na bhFiann.
1. A voiceless stop or /fˠ, fʲ/ is voiced:
Sound change | Normal | Urú | Gloss |
---|---|---|---|
/pˠ/ → /bˠ/ | práta /pˠɾˠaːt̪ˠə/ | bpráta /bˠɾˠaːt̪ˠə/ | "potato" |
/pʲ/ → /bʲ/ | peann /pʲaːn̪ˠ/ | bpeann /bʲaːn̪ˠ/ | "pen" |
/t̪ˠ/ → /d̪ˠ/ | tráta /t̪ˠɾˠaːt̪ˠə/ | dtráta /d̪ˠɾˠaːt̪ˠə/ | "tomato" |
/tʲ/ → /dʲ/ | teanga /tʲaŋɡə/ | dteanga /dʲaŋɡə/ | "tongue" |
/k/ → /ɡ/ | cat /kat̪ˠ/ | gcat /gat̪ˠ/ | "cat" |
/c/ → /ɟ/ | ceann /caːn̪ˠ/ | gceann /ɟaːn̪ˠ/ | "head" |
/fˠ/ → /w/, /v/ | focal /fˠɔkəlˠ/ | bhfocal /vˠɔkəlˠ/ | "word" |
/fʲ/ → /vʲ/ | freagra /fʲɾʲaɡɾˠə/ | bhfreagra /vʲɾʲaɡɾˠə/ | "answer" |
In the West Muskerry dialect, /sˠ/ and /ʃ/ are also voiced, but this is not reflected in the orthography nor is it standardised outside of that barony.[citation needed]
2. A voiced stop becomes a nasal:
Sound change | Normal | Urú | Gloss |
---|---|---|---|
/bˠ/ → /mˠ/ | bainne /bˠaːnʲə/ | mbainne /mˠaːnʲə/ | "milk" |
/bʲ/ → /mʲ/ | bean /bʲan̪ˠ/ | mbean /mʲan̪ˠ/ | "woman" |
/d̪ˠ/ → /n̪ˠ/ | droim /d̪ˠɾˠiːmʲ/ | ndroim /n̪ˠɾˠiːmʲ/ | "back" |
/dʲ/ → /nʲ/ | dinnéar /dʲɪnʲeːɾˠ/ | ndinnéar /nʲɪnʲeːɾˠ/ | "dinner" |
/ɡ/ → /ŋ/ | glúin /ɡɫ̪uːnʲ/ | nglúin /ŋɫ̪uːnʲ/ | "knee" |
/ɟ/ → /ɲ/ | geata /ɟat̪ˠə/ | ngeata /ɲat̪ˠə/ | "gate" |
3. A vowel receives a preceding /n̪ˠ/ or /nʲ/ (broad preceding a/o/u, slender preceding e/i). However, a vowel-initial word is not affected after the definite article an.
Sound change | Normal | Urú | Gloss |
---|---|---|---|
/e/ → /nʲe/ | éan /eːn̪ˠ/ | n-éan /nʲeːn̪ˠ/ | "bird" |
/i/ → /n̪ˠi/ | oíche /iːhə/ | n-oíche /n̪ˠiːhə/ | "night" |
The other consonants do not change under urú.
Environments of urú[]
After plural possessive pronouns[]
The possessive pronouns that trigger eclipsis are ár "our", bhur "your (pl.)", a "their"
- ár gcairde "our friends"
- bhur bpáistí "your (pl.) children"
- a mbád "their boat",
Note that a can mean "his", "her" or "their", but these different uses can still be distinguished, since a causes lenition when used as "his" (a bhád), causes eclipsis when used as "their" (a mbád), and neither when used as "her" (a bád).
After certain numbers[]
The numbers that trigger eclipsis (the noun being in the singular) are:
- seacht gcapall "seven horses"
- ocht n-asal "eight donkeys"
- naoi gcat "nine cats"
- deich bpeann "ten pens"
After the preposition i "in"[]
Before a vowel in is written instead of i n-.
- i dteach "in a house"
- in Éirinn "in Ireland"
Genitive plural nouns after the definite article[]
The genitive plural article na eclipses a following noun:
- na n-asal "of the donkeys"
- na bhfocal "of the words"
Dative singular nouns after the definite article[]
In western and southern dialects, nouns beginning with a noncoronal consonant are eclipsed after combinations of preposition + article in the singular (except den, don, and sa(n), which trigger lenition)
- ag an bhfear "by the man"
- ar an gcrann "on the tree"
After certain preverbal particles[]
- an poll a dtagann na coiníní as "the hole that the rabbits come out of"
- An dtagann sé gach lá? "Does he come every day?"
- Cá bhfuil mo spéaclaí? "Where are my glasses?"
- Dúirt sé go dtiocfadh sé. "He said that he would come."
- dá mbeadh a fhios sin agam "if I had known that"
Changes to vowel-initial words[]
A vowel-initial word does not change if a séimhiú is expected:
- an oíche "the night" (feminine singular nominative noun after definite article)
- an uisce "of the water" (masculine singular genitive noun after definite article)
- ó Albain "from Scotland" (noun after leniting preposition)
- seanathair "grandfather" (noun after preposed adjective: sean "old" + athair "father")
However, if neither urú nor séimhiú is expected, an initial vowel may acquire a prothetic onset consonant. For example, a vowel-initial masculine singular nominative noun requires a t- after the definite article:
- an t-uisce "the water" (masculine singular nominative)
Otherwise, there is the prothetic onset h, which comes only when both the following conditions are met:
- a proclitic causes neither lenition nor eclipsis of consonants.
- a proclitic itself ends in a vowel.
Examples of h-prothesis
- a haois "her age" (after possessive pronoun a "her"; compare with a aois, "his age" and a n-aois, "their age" with regular urú)
- go hÉirinn "to Ireland" (after preposition go "to, towards")
- le hAntaine "with Antaine" (after preposition le "with")
- na hoíche "of the night" (on feminine singular genitive noun after definite article)
- na héin "the birds" (on plural nominative/dative noun after definite article)
- chomh hard le caisleán "as high as a castle" (after chomh [xo] "as")
- go hálainn "beautifully" (after adverb-forming particle go)
- Ná himigh uaim "Don't leave me!" (after negative imperative particle ná "don't")
- an dara háit "the second place" (after an ordinal numeral)
