Vocative. The vocative plural is like the nominative plural, terminating in a, but seldom in an; as, fear m. a man, n. p. fir or feara, v. p. fheara; oglach m. a servant, n. p. oglaich, v. p. oglacha. Except perhaps monosyllables which never form their nominative plural in a, nor their dative plural in ibh; as, damh m. an ox, n. p. daimh, v. p. dhaimh; a shloigh, Rom. xv. 11.

General Rule for the Genitive. The genitive of polysyllables is like the nominative; of monosyllables is made by adding e to the nominative; as, caraid m. a friend, g. s. caraid; aimsir f. time, g. s. aimsir; tigh m. a house, g. s. tighe; ainm m. a name, g. s. ainme; im m. butter, g. s. ime; craig f. a rock, g. s. craige.

Particular Rules for the Genitive. 1. Feminine nouns in ail and air drop the i and add ach; if the nominative be a polysyllable, ai is thrown away; as, sail f. a beam, g. s. salach; dail f. a plain, g. s. dalach; lair f. a mare, g. s. làrach; cathair f. a seat, g. s. cathrach; nathair f. a serpent, g. s. nathrach; lasair f. a flame, g. s. lasrach. To these add còir f. right, g. s. còrach or còire.
