[THE DETERMINATIVE PRONOUN.]

[671]. The determinative pronoun is, that, the aforesaid, the one, is declined as follows:

	Singular.			Plural.
	Masc.	Fem.	Neut.	Masc.	Fem.	Neut.
Nom.	is	ea	id	eī, iī, or ī	eae	ea

Acc.	eum	eam	id	eōs	eās	ea
Abl.	eō	eā	eō	eīs, iīs, or īs	eīs, iīs, or īs	eīs, iīs, or īs

[672]. is and id ([659]) are formed from a stem -i-, and the other parts from a stem eo-, eā-. The genitive is sometimes written in Cicero and Plautus eiius; for the quantity of the first syllable of eius, see [153, 2]; for ĕ̄i, see [127, 3], and [127, 4].

[673]. In old verse, the genitive singular rarely has the first syllable short. Old and rare forms are: D. F. eae, Ac. M. im or em. Pl. D, and Ab. ī̆bus, F. eābus ([442]). In dramatic verse, e͡um, e͡am, e͡i, e͡o, e͡a, and e͡i, e͡orum, e͡arum, e͡os, e͡as, e͡is, are often found; also eccum, eccam, eccōs, eccās, ecca, for ecce eum, &c.

[674]. Other case forms of is are found in inscriptions, as follows:

N. EIS, 124 B.C. G. EIVS, EIIVS, EIIVS or EIIVS ([23]). D. EIEI, 123 B.C.; EEI, IEI; EI, 123 B.C., and common in all periods. Plural: N. EEIS, EIS, IEIS, till about 50 B.C.; EEI, EI, IEI. D. and Ab. EEIS, EIEIS, IEIS, IS; after the republic, IIS, IIS.

[675]. A rare and old pronoun equivalent to is is sum, sam, accusative singular, sōs, accusative plural, and sīs, dative plural.
