Morphology

April + Fools'

The phrase transparently combines 'April' and 'fools', so a learner who knows both words can infer it refers to a day in April associated with fools or joking. However, the specific convention—that it is observed on April 1 and involves playing practical jokes and hoaxes—is cultural knowledge not strictly predictable from the constituents, so full understanding requires prior exposure.

Etymology

One popular story says the tradition of April Fools' comes from an old calendar mix-up: when some people moved New Year's Day from April 1 to January 1, those who kept celebrating on April 1 were mocked as 'fools'. So today April Fools' is the day for playing 'pranks' and jokes.
