Editing Irish declension (section)

====Second====
The second declension is made up of mostly feminine nouns, and features a nominative singular form that can end in either a broad or a slender consonant.  The genitive singular ends in a slender consonant followed by ''-e''.  The most common plural form has a broad consonant followed by ''-a'' in the nominative, and a broad consonant alone in the genitive. The vocative has the same endings as the nominative, as does the dative in standard language.

In [[Connacht Irish]] and Waterford Irish it is often the case that all nouns of the second declension in the nom. sg. end with a slender consonant (e.g. {{lang|ga|bróig}} "a shoe").

In some Munster varieties as well as the old literary language, the dative singular is distinct and ends in a slender consonant alone (in effect the dative sg. is formed by dropping the ''-e'' from the genitive sg.), e.g. {{lang|ga|i mo bhróig}} "in my shoe" (historically, nominative forms like {{lang|ga|bróig}} are descended from the old dative).

When {{IPA|/x/}} in the gen. sing. is made slender, it is also voiced, so {{IPA|/x/}} > {{IPA|/ç/}} > {{IPA|/j/}}. {{IPA|/əjə/}} becomes {{IPA|/iː/}}, and is written '''-(a)í'''.
