april

1297, aueril, from O.Fr. avrill (11c.), from L. (mensis) Aprilis "(month) of Venus," second month of the ancient Roman calendar, dedicated to the goddess Venus and perhaps based on Apru, an Etruscan borrowing of Gk. Aphrodite. Replaced O.E. Eastermonað, which was similarly named for a fertility goddess. Re-spelled in M.E. on L. model (apprile first attested 1377). April Fool is attested from 1687. April-gowk (from O.N. gaukr "a cuckoo") is a northern variant. April Fool's Day customs of sending people on false errands seem to have come to Eng. from France late 17c.; originally All Fool's Day (1712). In Cumberland, Westmorland and northern parts of Lancashire and Yorkshire, however, May 1 was the day for hoaxing, and the fool was a May gosling. That custom was first attested 1791.
