Notes: Reconstructed for the PEC level. The initial syllable with a laryngeal was lost in most languages (except Av. and PC), but has left behind pharyngealisation in Lak. and PL. Av. ʕurč:ín- is a transformation of *ʕuč:ir- (probably the result of adding a secondary suffix -Vn-: *ʕuč:ri-n- > ʕurč:in-). The fate of *-l- in PTs is not quite clear.
