The word for “egg” in MTO is ḳáwḥəl, but only bīẓ̂áyt is attested in each of the three SAE volumes (see Kogan 2015: 499). Clear Arabism (Kogan 2015: 175)
Probably Arabism (MSA form) with ḏ̣ (< *ṯ̣) instead of the expected ẑ/ẓ̂ (< ṣ̂) (SED I – A. Militarev, L. Kogan; 2000).
həbyōḏ̣ ‘to lay an egg’ [JM 60]
