From Middle English felawe, felowe (“companion, good friend”) from Old English fēolaga, from Old Norse félagi, derived from félag (“joint venture; partnership”, literally “a laying together of property”), from fé (“livestock, property; money”) (ultimately from Proto-Indo-European *peḱ- (“livestock; wealth”)) + lag (“something laid down; right position; arrangement; companionship, fellowship; partnership”) (ultimately from Proto-Indo-European *legʰ- (“to lie down”)).
