eboreus (Latin)

Where does "eboreus" come from?

The Latin adjective 'eboreus', meaning 'ivory', is formed by combining the noun 'ebur' with the suffix '-eus'[1]. The root noun 'ebur' entered Latin as a loanword derived from Demotic 'ybbor'[2]. This term traces further back to the Egyptian 'ꜣbw', which denoted ivory, the elephant, or the place Elephantine[2]. Scholars link the origin of 'ꜣbw' to the Egyptian verb 'ꜣb', which means 'to tarry', 'avoid', or 'cease'[3].
