"used till so common as to have lost its novelty and interest," 1540s, from Latin tritus "worn, oft-trodden," of language "much-used, familiar, commonplace," past participle adjective from terere "to rub, wear down" (see throw (v.)). Related: Tritely; triteness.
hot-rodders' slang, 1952, perhaps from peel "blade or wash of an oar" (1875, American English), earlier "shovel-shaped instrument" (see peel (n.2). Or it might be from aircraft pilot phrase peel off "veer away from formation" (World War II), or from earlier American English slang peel it "run away at full speed" (1860).
mid-14c., "a kind of door latch," and said to be still the name for rings for raising thumb-latches in the north of England, appears to be what it looks like: what you say when you open the door ("have good day," as in the 1414 record of them as hafgooddays).
Usage examples of "haggaday".
