hippogonal

== English == === Etymology === The word was coined by David Parlett. It derives from Ancient Greek ἵππος (híppos, “horse, cavalry”) [a synonym in chess for knight] and γωνία (gōnía, “angle”). === Pronunciation === IPA(key): /hɪˈpɒɡənəl/ Rhymes: -ɒɡənəl === Adjective === hippogonal (not comparable) Being a move in a board game that is neither orthogonal nor diagonal, as a knight's move in chess. In chess, an (m,n) move spans m squares in one of the orthogonal directions and n squares in a perpendicular direction; the move is hippogonal if m and n are not equal and both greater than zero: 0 < n < m. === References ===
