According to Leslau [CDG 640], from Gez. (no argumentation given); cf.
zäläb id. [CDG 1608] with l, which Leslau also considers a loan from Gez. [CDG
640] (cf., however, [Leslau Loanwords 34], where the same word is considered an Arabism).
Attested sparsely in MTjŠ, alongside the other term for the concept, namely, ḏēl (Kogan 2015:522). The later term is, however, not attested in SAE III and IV, where ḏənūb is the only exponent for the meaning.
