Old English grædig (West Saxon), gredig (Anglian) "voracious," also "covetous," from Proto-Germanic *grædagaz (cognates: Old Saxon gradag "greedy," Old Norse graðr "greed, hunger," Danish graadig, Dutch gretig, Old High German gratag "greedy," Gothic gredags "hungry"), from *græduz (cognates: Gothic gredus "hunger," Old English grædum "eagerly"), possibly from PIE root *gher- "to like, want" (source of Sanskrit grdh "to be greedy").

In Greek, the word was philargyros, literally "money-loving." A German word for it is habsüchtig, from haben "to have" + sucht "sickness, disease," with sense tending toward "passion for."
