c.1300, from O.Fr. devin, from L. divinus "of a god," from divus "a god," related to deus "god, deity" (see Zeus). Weakened sense of "excellent" had evolved by late 15c. Divinity is from c.1300.
"to conjure, to guess," originally "to make out by supernatural insight," early 14c., from L. divinus (see divine (adj.)), which also meant "soothsayer." Hence, divination (late 14c.), from O.Fr., from L. divinationem (nom. divinatio) "the power of foreseeing, prediction," from divinatus, pp. of divinare, lit. "to be inspired by a god." Divining rod (or wand) attested from 1650s.
