The Lords of empty and full

The Kababish (lords of all they Survey, in their own Opinion)

-On Trek in Kordofan, C.E.A. Lea

Lane has the triliteral root R-’-Y generating both the Form I verb To Survey and the noun Opinion, and gives the definition of that root’s Form IV verb as “To become full in the udder”, which leads to my opinion that Lea’s opinion of Kababish opinion, consumate camel breeders of the empty desert, was informed more by IV than I.
