§§ 263-4] Pronouns 123
The reflexive pronoun originally referred to the chief person of the sentence (generally the subject), irrespectively as to whether the subject was the first, second, or third person singular or plural. This usage remained in Sanskrit, but in the Germanic languages the pronouns of the first and second person came to be used reflexively already in prim. Germanic, and then the original reflexive pronoun became restricted to the third person. In Goth, sik, seina, sis were used for both numbers and all genders. sik from prim. Germ, se+ke (§261), OHG. sih, cp. Gr. € from *σε, Lat. sē; seina is of the same origin as meina, þeina (§ 261); on sis see § 261.
3. Possessive.
§ 263. The possessive pronouns meins, my; þeins, thy; 'seins, his, are originally old locatives, Indg. *mei, *tei, *sei with the addition of the nominal suffix -no-, whence prim. Germanic masc. nom. *mīnaz, "þīnaz, *sīnaz; fern, nom. *mmō, *þínō, *sīnō. Only the ace. gen. dat. sing. and pi. of *seins occur. This form of the possessive pronoun is only used when it relates to the subject of its own sentence. When it relates to any word other than the subject of its own sentence, it is expressed by the gen. case of the personal pronoun masc. and neut. sing, is, plural izē; fern. sing, izōs, plural izō. The nom. of the third person for both sing, and plural all genders is expressed by the gen. case of the personal pronoun (§ 200). See § 431.
The remaining possessive pronouns were formed from the personal pronouns by means of the Indg. comparative suffix -ero-, prim. Germanic -era-, as unsar, our; "ugkar, of us two; izwar, your; igqar, of you two.
§ 264. The possessive pronouns are declined according to the strong declension like blinds (§ 226). The possessive pronouns ending in -ar do not have the form in
