Middle English April "April," from early French avrill and Latin Aprilis (both meaning "April")
The English word April comes from the Latin Aprilis, the name given to the month by the ancient Romans. No one knows for certain why the Romans named it as they did. Some Roman authors thought that Aprilis was related to the Latin verb aperire meaning "to open," because April "opened" the buds of leaves and flowers. A more likely theory is that the name was based on Apru, an Etruscan form of the name of the Greek goddess Aphrodite.
