PERIOD ( . )

The period is used at the end of a complete sentence, which can be a statement, command, or request. It is a visual marker to the reader that one complete thought has ended and that another may follow. In informal writing, periods can be used with single words.


Statement: Your bicycle is on my foot.

Request: Please move your bicycle off my foot.

Command: Get your bicycle off my foot.

Single words: Thanks. That feels much better.

Periods are also used in many abbreviations.
