Etymology

Origin unknown, first recorded in the mid 16th century, probably related to Latin flagrō (“I burn”). Norwegian flara (“to blaze; to flaunt in gaudy attire”) has a similar meaning, but the English word predates it. Possibly related to Middle High German vlederen (“to flutter”), represented by modern German flattern. The noun is derived from the verb.
