Where Does the Period Go?

If an entire sentence or group of sentences appears in parentheses, then put the period inside the closing parenthesis. This is a parenthetical sentence. Thus:

Parenthetically Enclosed Sentence

If parenthetically enclosed words end a sentence, then the period comes outside the closing parenthesis:

Parenthetical Words Ending the Sentence
He enjoyed all kinds of fruit (especially apples, oranges, and bananas).
