Representing the Nile crocodile (Crocodylus niloticus). The reason for the phonetic value jt is obscure, but Gardiner suggests it could come from the word’s use as a determinative in ꜣd(“to be angry or aggressive”) as sound changes brought this word closer in pronunciation to jt.
Determinative in words relating to crocodiles and their perceived qualities: ḥntj(“to be greedy”), skn(“greedy”), ꜥẖm(name of a demon, literally “Horrifier”), ꜣd(“to be angry or aggressive”), etc.
