Alteration (probably influenced by Greek sophos, wise, and mōros, stupid) of sophumer, from obsolete sophom, sophism, dialectic exercise, variant of sophism.(American Heritage® Dictionary of the English Language, Fourth Edition)
From earlier sophumer, from the obsolete sophom ("sophism or dialectical exercise"), likely influenced by Ancient Greek σοφός (sophos, "wise") + μωρός (mōros, "fool"). Compare oxymoron (literally "sharp-dull"), a similar contradiction. (Wiktionary)
