End Punctuation

There are three punctuation marks that come at the end of a sentence: the period ( . ), the question mark ( ? ), and the exclamation point ( ! ). A sentence is always followed by a single space, no matter what the concluding punctuation is.


The word period, followed by a period.Periods indicate a neutral sentence, and as such are by far the most common ending punctuation mark. They’re at the end of every sentence on this page so far. They occur at the end of statements.

Question Marks

Some questions are used principally as polite requests (Would you pass the salt?).

All of these questions can be categorized as direct questions, and all of these questions require a question mark at their ends.

Indirect Questions

Indirect questions do not have question marks at their ends. They can be used in many of the same ways as declarative ones, but they often emphasize uncertainty or lack of knowledge:

  • I can’t guess how Tamika managed it.
  • I wonder whether I looked that bad.
  • Cecil asked where the reports were.

Notice that different word order is used in direct and indirect questions: in direct questions, the verb usually comes before the subject, while in indirect questions, the verb appears second.

Exclamation Points

While this kind of statement is excessive, there are appropriate ways to use exclamation points. A sentence ending in an exclamation mark may be an exclamation (such as “Wow!” or “Boo!”), or an imperative (“Stop!”), or it may indicate astonishment: “They were the footprints of a gigantic duck!”

The exclamation mark is sometimes used in conjunction with the question mark convey protest or astonishment (“Of all the coffee shops, you want to meet at the Pied Cow?!”).

Exclamation marks may be repeated for additional emphasis (“That’s great!!!”), but this practice is generally appropriate only in casual or informal writing, such as text messaging or online communication with friends and family.


Are ending punctuation marks used appropriately in these sentences? Explain why or why not. The sentences have been numbered to aid you in your comments:

(1) One famous eighteenth-century Thoroughbred racehorse was named Potoooooooo, or Pot-8-Os! (2) He was a chestnut colt bred by Willoughby Bertie, 4th Earl of Abingdon, in 1773, and he was known for his defeat of some of the greatest racehorses of the time. (3) With a well-to-do background like this, where do you suppose his strange name came from.

(4) The horse once had a stable lad, who facetiously misspelled Potatoes. (5) Apparently, the owner thought the misspelling was funny enough to adopt it as the horse’s real name!

Punctuation Clusters

Occasionally, you’ll encounter cases that seem to require multiple punctuation marks right next to each other. Sometimes you need to keep all the marks, but other times, you should leave some out.

In general, you should not use more than one ending punctuation mark (period, question mark, exclamation point) in a row. If you are quoting a question, it should end with a question mark, not a question mark and a period. If an abbreviation, like etc., ends a sentence, you should use only one period.

  • Carlos leaned forward and asked, “Did you get the answer to number six?”
  • I think we’ll have enough food. Mary bought the whole store: chips, soda, candy, cereal, etc.

However, you can place a comma immediately after a period, as you can see above with etc. This rule also applies to the abbreviations e.g. and i.e.

Note: For those who are curious, e.g. is an abbreviation for the Latin phrase exempli gratia, which means “for example,” and i.e. stands for id est, which is Latin for “that is.”

Periods and parentheses can also appear right next to each other. Sometimes the period comes after the closing parenthesis, but sometimes it appears inside the parentheses. (This is an example of a sentence in which the period falls within the parentheses.) We’ll learn more about this in Brackets, Parentheses, and Ellipses.
