masc. proper name, in Old Testament, Jacob's youngest son (Gen. xxxv:18), from Hebrew Binyamin, literally "son of the south," though interpreted in Genesis as "son of the right hand," from ben "son of" + yamin "right hand," also "south" (in an East-oriented culture). Compare Arabic cognate yaman "right hand, right side, south;" yamana "he was happy," literally "he turned to the right." The right was regarded as auspicious (see left and dexterity). Also see Yemen, southpaw, and compare deasil "rightwise, turned toward the right," from Gaelic deiseil "toward the south; toward the right," from deas "right, right-hand; south." Also compare Sanskrit dakshina "right; south." Slang meaning "money" (by 1999) is from portrait of Benjamin Franklin on U.S. $100 bill.[Benjamin etymology, Benjamin origin, 英语词源]
