82 Phonology [§ '75 some cases was due to the influence of the corresponding strong verbs, as nasjan, for 'nazjan, after the analogy of nisan, cp. OE. nerian, OHG. nerien, to save; ur-ráisjan, to raise up, sv. ur-reisan, to arise, cp. OE. ræran, to raise; láisjan, cp. OE. læran, OHG. lēren, to teach; wasjan, to clothe, cp. OE. werian, OHG. werien, to wear, see § 137 note. Germanic final -z became -s in Gothic, as gen. đluz-is, riqlz-is, but nom. dius, wild beast; riqis, darkness; nom. sing, dags, from *đagaz, day; gasts from *gastiz, guest; nom. pi. dagos from *đagōz; gasteis from '§astīz; nom. sing, akrs from *akraz, field; nimis from *nimiz(i). thou takest. This -s was dropped when it came to stand after an original s through the loss of a vowel, as waírs from *wirs(i)s older *wirsiz (av.), worse, cp. adj. waírsiza, worse; nom. drus (gen. drusis) from *drusiz, fall; láus, empty, but gen. láusis; freihals, freedom, but gen. freihalsis. Final -s (-z) was dropped after a short vowel -I- consonantal r, cp. nom. sing, waír, man; baúr, son; anþar, second; unsar, our, &c., beside nom. sing, dags,day; gasts,guest; akrs,field; swērs, honoured; skeirs, clear; gen. brōþrs, of a brother, &c. Final -(i)z also disappeared in the dat. pi. (originally instrumental) ending of nouns, adjectives and pronouns, if we are right in assuming that the ending was originally •mis = prim. Germanic -miz, as in dagam, gibōm, gastim, brōþrum, blindáim, þáim. But the original ending may have been simply -mi. And similarly in the first pers. pi. of the pres. indie, which originally ended in -mes, -mos = prim. Germanic -miz, -maz (§ 287). NOTE.—i. The z, in such forms as rfqiz, darkness; mimz, flesh, meat, beside the regular forms riqis, mims, was due to the levelling out of the stem-form of the oblique cases. a. Final -z remained when protected by a particle, cp. e. g. wileiz-u? wilt thouf; @az-uh, each, every; iz-ei (rel. pr.), who;
