1300–50; Middle English hap
betide. Happen, chance, occur
refer to the taking place of an event. Happen
which originally denoted the taking place by hap or chance, is now the most general word for coming to pass: Something has happened. Chance
suggests the accidental nature of an event: It chanced to rain that day. Occur
is often interchangeable with happen
but is more formal, and is usually more specific as to time and event: His death occurred the following year.
