Comments: Av. has an irregular accent paradigm (gen. c̣:áda-l, pl. c̣:adá-l). Cf. also Akhv. Tseg., Tlan., Ratl. c̣:a, Cham. Gig. c̣:aj. The Av. and Akhv. forms contain historical suffixes (probably reflecting old obl. stems *c̣:adV-lV- and *c̣:adV-rV- - cf. the external evidence). Loss of medial *-d- in Andian languages is quite strange, but there seems to be no reason to suppose that *-d- is a suffix in all languages outside the Andian family (cf. a similar case in PA *la[d]i < PEC *ladV 'a k. of berry' q.v.).
