Notes: As seen from the Lak. and Darg. forms, the use of this root with class prefixes (*w-, reflected in Av. and Ud.) is probably secondary. Medial *-w- is reflected in Darg. as -b- and in PWC as labialisation. Pharyngealisation in Dargwa may be secondary (expressive); if it is not, *c̣HĂwnV should be reconstructed. See Абдоков 1983, 142.
