Middle English, alteration (perhaps influenced by Latin chalybs, steel) of Medieval Latin Caliburnus, from Middle Welsh Caletuwlch or Middle Irish Caladbolg, a legendary sword.(American Heritage® Dictionary of the English Language, Fourth Edition)
Middle English Excalaber, from Old French Escalibor, Escaliborc, prothetic form of Calliborc, alteration of Calibourne, from Medieval Latin Caliburnus (Geoffrey of Monmouth, ca. 1136), influenced by calibs ‘steel’ (for chalybs), alteration of Old Welsh *Caledbulch (cf. modern Caledfwlch), compound of caled ‘hard’ and bwlch ‘cleft, crack’. Related to the Irish legendary sword Caladbolg, literally ‘hard-belly’, i.e. ‘voracious’. (Wiktionary)
