Comment: The stem is verbal (and belongs to the strong verb class), but is often used for deriving adjectives 'high' (Rut. ha-χɨ-d, Tsakh. aχtɨ-n, Arch. b-e:χu) or 'long' (Kryz. ʕaχtä, Bud. ʕapχu, Ud. boχo). The meaning 'long' may be a result of partial contamination with PL *[hI]alχä- 'long' q.v., but in general these two roots are to be strictly kept apart.
