Dhibāb, Thin Clouds like Smoke. Dhibn, [Camel] Armpit. Dzibāb, [the Common Fly] the Black Thing that is in Houses and Falls into Vessels and Food
-Lane’s Lexicon, Entries for the triliteral roots Dh-B-B, Dh-B-N, and Dz-B-B
In Sudanese Arabic, the consonants Dh and Dz are pronounced as D, so the colloquial word I learned for Fly was Dibāba (sing.), Dibāb, Dibbān (pl.), and thus I heard the name of the village we passed early on the Darb as Um Dibbān, Mother of Flies, but later I saw it spelled as Um Dhibbān, which can be read as Mother of Thin Clouds or, with a bit of linguistic license, Mother of Armpits. If it wasn’t Mother of Flies, I knew how KhairAllah must have heard it, for he didn’t like the smell of Um Dibbān either.
