An Etymological Dictionary of the German Language/mein

by Friedrich Kluge

mein, poss. pron., ‘my,’ from MidHG. and OHG. mîn; in the same form it is the common Teut. poss. pron. from the stem me- of the pers. pron. (mir, mich, thus even in MidHG. and OHG.). This stem me- (in Goth. mi-s, ‘to me,’ mi-k, ‘me,’ acc.) is according to Lat. meus, mihi, Gr. μέ, Sans. ma, common to the Aryan division. Further details belong to grammar.
