Etymology
Borrowed from Middle French refutation (compare French réfutation, Spanish refutación, Portuguese refutação, Italian refutazione) or directly from its source Latin refūtātiō, from refūtō + -ātiō. By surface analysis, this is refute + -ation. It is first recorded in 1536, in its first sense.
