gladiator: [16] The main Latin word for ‘sword’ was gladius. It was probably borrowed from a Celtic word, in which case its relatives would include Irish claideb, Welsh cleddyf, and Scots Gaelic claidheamh (which with the addition of mór ‘great’ produced English claymore [18]). Among its derivatives were gladiātor, literally ‘swordsman’, and gladiolus, literally ‘little sword’, acquired by English in the 16th century. => claymore, gladiolus
