Arabic

ˀaslaˁ- - leper, who has scaly skin (BK I 1125)

The by-form with γ in Arb. permits an alternative reconstruction with *γ as the third radical since the rest of the languages do not distinguish between the reflexes of *ˁ and *γ.

PS
*š/sVl(V)ˁ- - (kind of) disease causing scales on the skin; leprosy (SED I No. 243)
