Usage: Use finite to describe anything that has a definite beginning and end, such as time, resources, or the number of items in a group. This word contrasts with infinite concepts where no limit exists, making it essential for distinguishing bounded quantities from unbounded ones.
Finite comes from the Latin finitus, meaning "finished" or "terminated," which originally referred to a boundary before entering Middle English as finyté. This term eventually replaced the Old English word geendodlic in common usage.
