Appendix:Irish second-declension nouns

The Irish second declension is made up primarily of feminine nouns; there are only three masculine nouns. The nominative singular ends in a broad (velarized) or slender (palatalized) consonant. The genitive singular is formed by adding -e to the nominative singular and palatalizing the final consonant if it is not already slender.

The vocative and dative singular are identical to the nominative singular. (However, in the archaic literary language and in some dialects, the second declension has a distinct dative case formed by dropping the -e from the genitive singular but retaining the slender consonant.)

The plural can be formed in any of a variety of ways, which can be grouped into two basic types: the weak plural forms and the strong plural forms.

Weak plurals

edit

A weak plural in Irish is a plural formation in which the genitive plural is distinct from the nominative plural. The weak nominative plural is formed by adding -a to the broad consonant (for example, póg (a kiss) has nominative plural póga and deoir (tear) has nominative plural deora). The genitive plural is formed by dropping the -a of the nominative plural, e.g. póg (identical to nominative singular), deor (distinct from nominative singular). The vocative and dative plural are identical to the nominative plural. (However, in the archaic language and in some dialects the dative plural is formed by adding -aibh to the broad consonant, e.g. pógaibh, deoraibh.)

Strong plurals

edit

A strong plural in Irish is a plural formation in which the all cases of the plural are identical (except for the archaic and dialectal dative plural in -(a)ibh). Many words of the second declension form a strong plural with one of the endings -(e)anna, -í, -(e)acha, -ta, -te, -tha.

Vocative a áit a áiteanna

A few nouns undergo syncope of an internal syllable in the genitive singular and/or the plural:

Duals

edit

Some nouns referring to things that usually occur in pairs have a separate dual form that is used when the word is modified by dhá (two). It is identical in form to the (archaic) dative singular (i.e. it is formed by dropping the -e from the genitive singular). Moreover, in these words the dative singular is not archaic, but is commonly found.

All of these nouns have a weak plural.

Singular Dual Plural Gloss
Nominative Genitive Dative Nominative Genitive
bos boise bois dhá bhois bosa bos palm of the hand
bróg bróige bróig dhá bhróig bróga bróg shoe
cluas cluaise cluais dhá chluais cluasa cluas ear
cos coise cois dhá chois cosa cos a foot, leg
lámh láimhe láimh dhá láimh lámha lámh a hand

In some dialects, the dative singular of these nouns is also used as the nominative singular.

Masculines

edit

There are three masculine nouns in the second declension. All three have strong plurals.
