From Proto-Indo-European *h₂emseh₂ (“handle”), from *h₂em- (“to grasp”). Compare Lithuanian ąsa (“jug handle”), Proto-Germanic *ansijō (“handle, loop, eyelet”), Ancient Greek ἡνία (hēnía, “rein, bridle”). See also amplus (“ample”), ampla (“handle”), which the word was traditionally linked to, but which are not considered cognate anymore based on modern analysis.
