Etymology

It is inherited from Middle English sustenen, borrowed from Old French sustenir (“to hold up, endure”) (modern French soutenir),[2][3][4][5] from Latin sustineō (“to hold up, support, endure”), from sub- (“up from below”) and teneō (“to hold”) (see tenant),[2][3][5][6] from Proto-Indo-European *ten- (“to stretch”).[3]
