blazer

Origin

From Middle English blaseyr (“one who blazons coats of arms”), probably from blasen (“to inscribe with armorial bearings, emblazon; to blazon a coat of arms”) + -er, -ir (suffix forming agent nouns). Blasen is probably derived from blason, blasoun (“shield usually with a coat of arms; coat of arms”), from Old French blason (“shield; coat of arms”) (modern French blason); further etymology uncertain, probably from Frankish *blãsjan (“to light up, brighten, illuminate”), from Proto-West Germanic *blasā (“a flame, blaze; a firebrand, torch”) (see further at etymology 1). By surface analysis, blaze (“(heraldry) to blazon”, verb) + -er (suffix forming agent nouns).
