Etymology
The word 'zany' entered English in the late 16th century from the Italian 'zanni', a dialectal form of 'Gianni', a common Italian equivalent of 'John'. In the commedia dell'arte, a form of Italian improvisational theater, 'Zanni' was a stock character who was a comically clumsy servant and buffoon. The name, through its theatrical association, became a generic term for a foolish jester or mimic. Over time, the meaning broadened from a noun for a specific type of clown to an adjective describing anyone or anything that is eccentrically funny or ludicrous in a slapstick manner.
Analysis
The word is a simplex loanword from Italian. It cannot be meaningfully segmented into smaller morphemes within modern English spelling.
