Combining form

borrowed from Greek, combining form of autós "self, the same" (also as third person pronoun), of uncertain origin

Note: For autós R. Beekes posits as the Indo-European forerunner *h2eu̯- "again" + *to- "that" (see that entry 1); *h2eu̯- alone is the source of Greek "again, another time, in turn, next" (Etymological Dictionary of Greek, Brill, 2009). G.E. Dunkel, who accepts Indo-European *a as a vowel and does not believe that all words must begin with a consonant, subsumes the first element of autós under *au̯- "away, off" (*au̯-tó- would hence originally have been a deictic, "the one over there") and subsumes Greek under *h2u-, by-form of *h2o- "with it, at it, and, also" (Lexikon der indogermanischen Partikeln und Pronominalstämme, Heidelberg, 2014). Older etymological proposals (as a link between au- in autós and Sanskrit ásuḥ "life") are summarized by E. Schwyzer in Griechische Grammatik (Munich, 1990 [1938]), pp. 613-14.
