[649]. Older forms for vestrū̆m and vestrī are vostrūm and vostrī. The genitive plural was originally a genitive of the possessive: that in -ī being the neuter singular, that in -ū̆m the masculine or feminine plural. In old Latin, nostrōrum, nostrārum, vostrōrum, vostrārum also occur.
[650]. Emphasis is given (1.) by reduplication ([189]): Ac. and Ab. mēmē, tētē, rare; sēsē, very common. (2.) by -te added to the N. of tū: tūte. (3.) by -met added to any case but the genitive plural: as, egomet; but tū has only tūtemet or tūtimet.
[651]. In inscriptions, the datives MIHEI, TIBEI, and SIBEI occur, so written in verse sometimes even when the last syllable is short; and MIHE, TIBE. Plural: D. and Ab. VOBEIS. Ac. ENOS in an old hymn; SEESE ([29, 1]).
[THE PERSONAL AND REFLEXIVE POSSESSIVE.]
[652]. The possessives of ego, tū, and suī, are meus, mine, tuus, thine, and suus, his, her, its, their (own), declined like bonus ([613]), except that meus has mī in the vocative singular masculine ([459]); those of nōs and vōs are noster, our, and voster, later vester, your, declined like aeger ([617]).
[653]. Old forms are tuos, tuom, and suos, suom ([452]). In old verse me͡us, me͡i, &c., tu͡os, tu͡i, &c., su͡os, su͡i, &c., often occur. sōs for suōs, sās for suās, and sīs for suīs, are old and rare.
[654]. Other case forms are found in inscriptions, as follows:
MEEIS, MIEIS, monosyllable; TOVAM; SVEI, SOVOM, SOVO, SVVO, SOVEIS, SVEIS, SVIEIS.
[655]. Emphasis is given (1.) by -met added to suō, suā, suōs, and to mea and sua, neuter plural: as, suōmet; (2.) by -pte, which is oftenest found with the ablative: as, suōpte.
