Is Tuesday named for a one-handed god?
god of love, late 14c., from Greek eros (plural erates), literally "love," related to eran "to love," erasthai "to love, desire," of uncertain origin.
Freudian sense of "urge to self-preservation and sexual pleasure" is from 1922. Ancient Greek distinguished four ways of love: erao "to be in love with, to desire passionately or sexually;" 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.
Eros E·ros or e·ros (ěr'ŏs, ēr'-)
