Old Irish/Morphology/Nominal Proclitics and Particles
A general guide to clitic and particle morphemes, allomorphs and morphosyntactical structures in Old Irish noun phrases.
The Vocative Particle
Nouns in the vocative are always preceded by the vocative particle aL (var. áL), e.g. a ḟir ‘o man’. There is no inflectional variation in the particle and it only lenites.
The Dual Numeral
Nouns in the dual are always preceded by the dual numeral.
The masculine form of the dual is daL (var. dáL) in the nominative, accusative and genitive, e.g. da ḟer ‘two men/of two men’.
The neuter form of the dual is daN (var. dáN) in the nominative, accusative and genitive, e.g. da n-armm ‘two weapons/of two weapons’.
The feminine form of the dual is diL (var. díL) in the nominative and accusative, e.g. di thúaith ‘two tribes’. The feminine form of the dual is daL (var. dáL) in the genitive, e.g. da thúath ‘of two tribes’.
The masculine, neuter and feminine form of the dual is dibN (var. díbN, deibN) in the dative, which is always preceded by a preposition (or a combination of a preposition and the article), e.g. la dib n-armm ‘with two weapons’.
The dual never applies to nouns in the vocative; the plural form of the noun is used instead.
