||Kent (1953:193) defines OP nar- as 'man', but in Achaemenid Old Persian, the lexeme is attested only in the form ūvnara- 'skill, accomplishment'. Cf. Darius, Naqš-i Rustam b., ll. 51-2, ūvnarā ciyākaram=ca maiy '...and of what sort my skillfulnesses...' (Kent 139-40).
Some OP onomastic tokens (found in Elamite, Babylonian, etc. sources) contain *nar-, e.g., Elamite Na-ra-ik-ka, but these are exclusively proper names.
