Full stops

Try to split long sentences into shorter ones. Shorter sentences make text easier to read. Use one space, not two, after full stops.

Never put two full stops in a row.

Never put a full stop after a web address as it will be thought it is part of the address.

Questions and exclamations

Use question marks and exclamation points instead of a full stop, not in addition to one, even in quotations.

A sentence that stands alone within brackets needs a full stop inside the parentheses with it. (Here is an example.)

A sentence in parentheses within another sentence does not take a full stop, because the full stop is reserved for the main sentence

(Questions and exclamations, however, must have their respective marks!).

A sentence containing a parenthesis must itself have terminal punctuation (are we almost done?).

Finally, an abbreviation ending with a full stop that is immediately followed by a question mark or exclamation point requires both marks (Q.E.D.!).
