mid-14c., "praise, honor, extol" (God or a person), also "vaunt, be proud of, boast of; glorify oneself, be proud, boast;" from Old French glorefiier "glorify, extol, exalt; glory in, boast" (Modern French glorifier), from Late Latin glorificare "to glorify," from Latin gloria "fame, renown, praise, honor" (see glory (n.)) + -ficare, from facere "to make, do" (see factitious). From mid-15c. in non-theological sense, "praise highly." In Chaucer also "to vaunt, boast," But this sense has faded in English. Related: Glorified; glorifying.
