Lak root: w-iχ-
Meaning: believing, convinced
Lak form: wiχ-s:a
Comments: Cf. Khosr. wiχ xun 'to believe'. Initial w- is a former class marker. Although -χ is in the position of neutralisation in all known Lak. forms, the old Archi loanword wiχ kes 'to believe' (wiχ: as 'to make believe, convince') shows that PL had *-χ: in this root.
