Old Aramaic

lḥy - bad (DNWSI 571)

PArm
*lḥy - (to be) bad (Kogan 2015:427)

The root *lḥy ‘(to be) bad,’ of uncertain etymology, is still relatively well attested in Official Aramaic (DNWSI 571), but has been gradually replaced by *bˀš (HALOT 1830‒1831, DJPA 102, LSyr. 57, Jastrow 1988:183) and ceased to exist in later Aramaic dialects.
