From Middle French, from Old French -omes, -umes (first-person plural present indicative ending), of obscure and disputed origin. Possibly derived from the Frankish termination *-ōmēs, *-umēs (first-person plural present indicative ending), from Proto-Germanic *-ōmaz, *-amaz, related to Old High German -ōmēs, -umēs, Old Norse -um, Gothic -𐌿𐌼 (-um), -𐌰𐌼 (-am). Compare Occitan -èm, -am, -im, -em; Latin -āmus, -ēmus, -imus, īmus.
