1. acia — de Vaan
acia 'thread or yarn' [f. a] (Titinius+) It is generally assumed that acia must be derived from acus 'needle', but the semantics are not obvious: a thread is not sharp. One may think of a meaning 'which belongs to a needle', of course; but then one would rather expect *aku-ja-. BibL: WH I: 8, EM 5f., IEW 18ff. — [de Vaan, s.v. acia, p. 37]
