masc loc sg of atta (noun)
Etymology. From Indo-European *h₂et-mo- (reflexive pronoun). Cognate with Sanskrit ātman (self, soul), Latin ātum (past participle suffix suggesting the reflexive), and English dialect "it" in its earlier reflexive sense. The word evolved from a demonstrative particle to express the autonomous self or essential nature.
