[THE PRONOUN OF IDENTITY.]
[676]. The pronoun of identity, īdem, the same, is declined as follows:
| Singular. | Plural. | |||||
|---|---|---|---|---|---|---|
| Masc. | Fem. | Neut. | Masc. | Fem. | Neut. | |
| Nom. | īdem | eadem | idem | eīdem or īdem | eaedem | eadem |
| Gen. | eiusdem | eiusdem | eiusdem | eōrundem | eārundem | eōrundem |
| Dat. | eīdem | eīdem | eīdem | eīsdem or īsdem | eīsdem or īsdem | eīsdem or īsdem |
| Acc. | eundem | eandem | idem | eōsdem | eāsdem | eadem |
| Abl. | eōdem | eādem | eōdem | eīsdem or īsdem | eīsdem or īsdem | eīsdem or īsdem |
[677]. In manuscripts and editions, the plural nominative masculine is often written iīdem, and the dative and ablative iīsdem. The singular nominative masculine is rarely eisdem or isdem (Plaut., Enn.), eidem (Cic., Varr.), neuter īdem (Plaut.). In verse, eundem, e͡andem, e͡idem, e͡odem, e͡adem, and e͡idem, e͡aedem, e͡orundem, e͡osdem, e͡asdem, are often found.
[678]. Other case forms of īdem are found in inscriptions, as follows:
N. M. EISDEM, 123 B.C., ISDEM, 59 B.C., both common till Caesar’s time; EIDEM; Ne. EIDEM, 71 B.C. D. IDEM. Plural: N. M. EISDEM, ISDEM, EIDEM, till Caesar’s time; IIDEM, once only. D. and Ab. ISDEM, very rarely IISDEM.
[THE INTENSIVE PRONOUN.]
[679]. The intensive pronoun ipse, himself, stems ipso-, ipsā-, is declined like ille ([666]), but has the nominative and accusative neuter singular ipsum.
[680]. In dramatic verse, ipse has rarely the first syllable short, and often has the older form ipsus. Plautus has these forms: N. F. eapse, Ac. eumpse, eampse, Ab. eōpse, eāpse, equivalent to ipsa, &c. So reāpse for rē ipsā.
