neither rhyme nor reason

No sense whatever. This term dates from the fifteenth century, when an unknown French writer wrote, En toy ne Ryme ne Raison (“In you neither rhyme nor reason,” Maistre Pierre Pathelin, ca. 1475). Sir Thomas More is credited with the following remark made to a friend who had put into verse a mediocre book: “Yea, marry, now it is somewhat, for now it is rhyme; whereas before it was neither rhyme nor reason.” The term made it into John Ray’s proverb collection of 1678 and is by no means obsolete.
