Old Irish i-stem nouns.

These nouns are masculine, feminine or neuter, typically with the following endings:

• in the nominative singular: the bare stem (always ending in a palatalized consonant), with lenition of the following word when feminine, nasalization when neuter;
• in the genitive singular: -o or -a (sometimes with lowering or other modification of the stem vowel), with depalatalization of the final stem consonant and aspiration/gemination of the following word;
• in the nominative plural: when masculine or feminine, -i (or often -ai, with depalatalization of the final stem consonant), with aspiration/gemination of the following word; when neuter, -e, with lenition of the following word.

The stem classes are named from the perspective of Proto-Celtic and may not still be visible in Old Irish inflections.
