Crazy

KRAYZ-ee/ˈkreɪzi/

Crazy is informal for not sensible, or very strange: a crazy idea, drive someone crazy, crazy about football (very keen). Mad is a British cousin in the “keen” and “not sensible” senses. Insane is stronger and more medical — avoid for everyday A2. Do not use crazy as a clinical word about illness.
