Sanu’a reproduced Nubians in caricature rather than studying their actual speech

Evidence

Nowhere does the author, a linguist, seem to have studied their dialect as carefully as he did that of Upper Egyptians and the Lebanese. His knowledge of Turkish, which he displays continuously as the rulers of Egypt mangle Arabic, reveals an impressive awareness of Turkish conjugations. The Nubians speak a bastardized Cairene dialect, and even their attempts at love and its poetry raise the eyebrows of Sanü`a’s Egyptians. — Eve M.
