122 Accidence [§262 OHG. dih), the Goth. ace. and dat. had u from the nominative; *þes:*þiz (OS. thí, OHG. dir); *jūs (Lith. jus): *juz, Goth, may represent either form. It is doubtful what were the original forms of izwis and igqis (OE. inc, OS. ink). Norn. sing, is (Lat. is); in-a (O.Lat. im, OS. ina, OHG. in), the final -a from prim. Germanic -ō is originally a preposition governing the ace. case like Skr. a, up to, used after accusatives ; and similarly in ita, þata, þana (§ 265), hmna (§ 273), the -ō is regularly preserved in híanōh (§ 275), hrarjanōh, hmrjatōh (§ 276), þishianōh (§ 276); it-a (Lat. id, OS. it, OHG. ί-ζ); gen. is from Indg. *eso (OHG. OS. is with i from in, ίς ; ina, it); imma from the Indg. instr. *esmē, -ō (OS. OHG. imu, -ō) with the assimilation of -sm· to -mm- after vowels; and similarly in þamma (§ 265), ruamma (§ 273), hrammēh (§ 275) where the -ē is regularly preserved, eis, ins, im (OS. OHG. im), neut. nom. ace. pi. ija, from prim. Germanic *īs, ins, im·, *ijō older *ijā; izē, formed from the gen. sing, is -f the gen. ending -ē (§§ 87 (i), 179), and similarly OS. OHG. iro with -o from older -on. The original Indg. gen. pi. was *eisðra which would have become *eizō in Goth, and *īro in OS. OHG. *sī(Gr. I, O.lr. OHG. sī) : *si (Goth. OHG. si); ija from *ijōn older *ijām (cp. banđja, § 193); izōs from *ezoz older "esas (cp. gibōs, § 191); izái = Indg. *esāi (cp. gibái); ijōs = Indg. *ijās (cp. bandjōs); izō, formed from the iz- in the gen. sing. + the gen. ending -ō, cp. the similar formation of OS. OHG. iro. The regular form would have been *eizō, see above. § 2Θ2. 2. Reflexive. Ace. sik, oneself Gen. seina Dat. sis
