The Irish fifth declension is made up primarily of feminine nouns; however, male familial nouns (e.g. athair), and the ordinals 20, 30 etc. (e.g. fiche, tríocha) are masculine. The nominative singular can end in: slender consonants -il, -in(n), -ir; a vowel.

The fifth declension is characterised by the genitive singular ending in a broad consonant (depalatised). The dative tends to be slender (palatised).

The fifth declension plurals are predominantly strong plural with a few exceptions.
