The story

Picture an ancient Greek trying to separate a genuinely good argument from verbal fog: the key word was λόγος (lógos), which could mean a word, a speech, a rational explanation, or reason itself. That wonderfully crowded meaning produced λογικός, “pertaining to reasoning,” and eventually λογική, the “reasoning art.” By the 13th century, the term was circulating as Old French logique before Middle English writers adopted logike and logik; it displaced native expressions such as Old English flitcræft, literally “the art of arguing.” The word’s family still leaves fingerprints everywhere: a dialogue is a speech between people, a monologue is speech by one, and a syllogism is a carefully linked chain of reasoning. So logic is, at heart, the ancient Greek art of making words behave like evidence rather than smoke.
