Lenition (séimhiú)
editEffects of séimhiú
edit- A stop becomes a fricative. Voicing is retained, as is place of articulation except with the coronals.
- /p/ → /f/
- /t/ → /h/
- /k/ → /x/
- /b/ → /v/
- /d/ → /j/
- /ɡ/ → /ɣ/
- /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.
- /f/ is 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.

Environments of séimhiú
editAfter proclitics
editAfter the definite article
editThe definite article triggers lenition of:
- a feminine noun in the nominative singular
- an vișano "the girl"
- 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.)
