Full Stop
Full Stops
Full stops are used to mark the end of sentences. Sometimesthey are used to indicate abbreviations and acronymsor as a decimal point to separate numbers.
Read on to learn more about the different uses of the full stop in English texts.
Full Stop/Period
Use a full stop (also called a period) to end sentences. Use full stops frequently. They provide structure and clarity to a textand can help with readability.
- Example:
- I go shopping every day.
- I looked outside. It was raining again.
Use a full stop rather than a question mark to end indirect questions. (We only use a question mark if the indirect question is part of an actual question.)
- Example:
- I wonder what Mark is doing now.
- I asked her what time she was arriving.
- Can you tell me where the train station is?
Full Stops with Abbreviations
The use of full stops after abbreviations differs between British and American English. In British Englishfull stops are not used after abbreviationswhereas in American English they usually are.
| British English | American English | |
|---|---|---|
| Mister | Mr | Mr. |
| kilogram | kg | kg. |
| street | St | St. |
Full stops aren’t generally used when the abbreviation is written in capital letters or when it is an acronym.
- Example:
- BBC (the British Broadcasting Corporation)
- ATM (Automated Teller Machine)
- NATO (North Atlantic Treaty Organization)
Howeverin American English full stops are often placed after letters to indicate abbreviations.
- Example:
- U.S.A. (The United States of America)
- J.R. Dixon (John Russell Dixon)
If you are unsuremost common or well known abbreviations and acronyms can be found in a dictionary. Remember that consistency is important. Choose one and stick to it.
Decimal Point
Use a decimal point to separate dollars from centsand whole numbers from decimals.
- Example:
- $3.48
- 99.9% fat free
- The average Irish family has 1.38 children.

Ellipsis
An ellipsisor dot-dot-dot as it is colloquially knownis a series of three full stops. It has two main functions in English.
Firstlyit is used to indicate that a section of text has been omitted from a quoteusually to make it shorter.
- Example:
- “My role in society … is to try and express what we all feel. Not to tell people how to feel. Not as a preachernot as a leaderbut as a reflection of us all.” — John Lennon.
Secondlyan ellipsis can represent a pauseuncertainty or a trailing off of thoughts.
- Example:
- But maybe we could … Or perhaps if we … Oh never mindit’s too difficult. I guess we’ll never solve this problem …
An ellipsis should be treated like the word or text it replaces; this means we use a space either side andif it replaces the end of a sentencethe following word should start with a capital letter.
Many fonts and computer programs have an ellipsis symbol that can be inserted.
