autós

aut--ós, au--tós Sprachstufe:agr. 'selbst, derselbe, selbiger, …'

Laut Beekes aus einem uig. *h₂ew „noch einmal“ + *to- „das“. Risch leitet es von den altgriechischen Reflexen dieser Wörter ab: αὖ aû, „zurück, wieder, andere“ +‎ τόν tón, „das“. Verwandt mit dem phrygischen αυτος (autos) und stellt daher wahrscheinlich eine gemeinsame Neuerung dar.

Pronunciation IPA^(key): /au̯.tós/ → /aɸˈtos/ → /afˈtos/

Usage notes

The intended sense of αὐτός is generally defined by its grammatical context. When used as a lone nominal without an article, it is generally the third person personal pronoun. When appended to a nominal and not possessing the definite article it is "self". When combined with the definite article, either appended to a nominal or on its own, it is "same".

The neuter plural ταὐτά (tautá, “the same things”) (derived from τὰ αὐτά by crasis) is distinguished from ταῦτα (taûta) "these things" by the accent placement. The two sometimes occur together:

386 BCE – 367 BCE, Plato, Meno 85e:

οὗτος γὰρ ποιήσει περὶ πάσης γεωμετρίας ταὐτὰ ταῦτα, καὶ τῶν ἄλλων μαθημάτων ἁπάντων

hoûtos gàr poiḗsei perì pásēs geōmetrías tautà taûta, kaì tôn állōn mathēmátōn hapántōn

For he will do the same as this with all geometry and every other branch of knowledge.
