Etymology: "Kookish" is simply "kook" with the suffix "-ish" added, meaning "somewhat like a kook." The suffix "-ish" comes from Old English "-isc," used to form adjectives meaning "of the nature of" or "rather like" something, as in "childish" or "reddish." The base word "kook" is the more intriguing half. It is a slangy American term for an eccentric or odd person, and its own origins are tied to the idea of a person who is strange or unpredictable enough to seem a little crazy. Adding "-ish" softens the label, so that "kookish" describes behavior that is peculiar or whimsical rather than calling someone outright a kook.
