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.

gladiator (n.)youdaoicibaDictYouDict
mid-15c., "Roman swordsman," from Latin gladiator (fem. gladiatrix) "fighter in the public games; swordsman," from gladius "sword" (there is no verb *gladiare), which probably is from Gaulish (compare Welsh cleddyf, Cornish clethe, Breton kleze "sword;" see claymore). Old Irish claideb is from Welsh.
The close connection with Celtic words for 'sword', together with the imperfect match of initial consonants, and the semantic field of weaponry, suggests that Latin borrowed a form *gladio- or *kladio- (a hypothetical variant of attested British Celtic *kladimo- 'sword') from [Proto-Celtic] or from a third language.
