refutation
n. US //ˌɹɛfjuˈteɪʃən// UK //ɹɪfjuːtˈeɪʃən// refu·ta·tion
Borrowed from Middle French refutation (compare French réfutation, Spanish refutación, Portuguese refutação, Italian refutazione) or its etymon Latin refūtātiō, from refūtō + -ātiō. By surface analysis, refute + -ation. First attested in 1536 (in sense 1).
