Did You Know?
Acronym was created by combining acr- ("beginning") with -onym, ("name" or "word"). You may recognize -onym in other familiar English words such as pseudonym and synonym. English speakers borrowed -onym directly from the Greek (it derives from onyma, the Greek word for "name"). Acr- is also from Greek, but it made a side trip through Middle French on its way to English.
