Simplified etymology

Crazy derives from craze, a later medieval verb originally meaning “to break in pieces” or “shatter.” Crazy consequently first meant “broken” or “damaged,” and also “frail, unwell, or infirm,” before being applied figuratively to shattered sanity.

Etymology

From craze (“to crush”) + -y, akin to being "crazed up". Compare cracked up (“suffered a mental breakdown; be insane”), crackpot. Compare typologically Russian чо́кнутый (čóknutyj).
