Obs. exc. dial. Also kam, (7 kamme). [Adopted from Celtic: in Welsh cam crooked, bent, bowed, awry, wrong, false; Gael. cam crooked, bent, blind of one eye; Manx cam (as in Gaelic); Ir. cam:OIr. camm crooked, repr. an OCeltic *cambo-s, as in the proper name Cambodunum crooked town. In English probably from Welsh, and no doubt in oral use long before the 16th c. when first found in literature; the derived form cammed is in the Promptorium.]
