Punctuation

Punctuation provides vital clues that aid reader comprehension. It’s governed by well documented rules. For example, every English sentence requires end punctuation (unless it’s a title or a heading). Within those rules are stylistic choices, which we’ll cover here.

The more punctuation you add, the more complex a sentence becomes. If a sentence contains more than a comma or two and ending punctuation, consider rewriting it to make it clearer and more succinct.
