vile (adj.)
late 13c., "morally repugnant; morally flawed, corrupt, wicked; of no value; of inferior quality; disgusting, foul, ugly; degrading, humiliating; of low estate, without worldly honor or esteem," from Anglo-French ville, Old French vil "shameful, dishonorable; low-born; cheap; ugly, hideous," from Latin vilis "cheap, worthless, base, common," of uncertain origin, perhaps from PIE root *wes- (1) "to buy, sell" (see venal). Related: Vilely; vileness; vilety (early 13c.).
