On some cognates of Avestan hakat

Abstract This article deals with a number of Middle and New Iranian words of doubtful etymology for which a derivation from Ir. *hakat ‘together, at once’ is proposed. Its possible reflexes in Western Iranian witness a development towards a conditional or temporal meaning (Parth. ag ‘if’, NP aknūn ‘now’), but remnants of the old meaning ‘together’ can be identified in MP ag(e)nēn ‘together’ and in the Arm. loanword hakaṙak ‘opposite, against’. In Eastern Iranian it seems to have undergone grammaticalization and developed into a preverb (Khot. gga‑) or a preposition (Sogd. ku ‘towards’, Orm. ku- ‘to, on, etc.’, Ishk. kI ‘to, on, for’, Zeb. ka ‘id.’). Especially in this latter group of languages, Ir. *hakat shows an evolution largely comparable to that of *hačā ‘from’, which, according to most scholars, belongs to the same root.
