god of love, late 14c., from Gk., lit. "love," related to eran "to love," erasthai "to love, desire," of unknown origin. Freudian sense of "urge to self-preservation and sexual pleasure" is from 1922. Ancient Gk. distinguished four different kinds of love: eros "sexual love;" phileo "have affection for;" agapao "have regard for, be contented with;" and stergo, used especially of the love of parents and children or a ruler and his subjects.
