In the world of punctuation, the terms 'full stop' and 'period' often lead to a bit of confusion. Are they two different marks? Do they serve different purposes? Or are they simply two sides of the same punctuation coin? This article aims to demystify these terms, offering clarity on their usage and significance in different variants of the English language.

Full Stop and Period: More Similar Than Different

At their core, the full stop and the period are the same punctuation mark – a small dot (.) used to indicate the end of a sentence. The primary difference lies not in their function but in their nomenclature, which varies based on whether you're using British English or American English.

Full Stop: The British Term

In British English, the term 'full stop' is used to describe this punctuation mark. It signifies the end of a sentence, indicating a complete stop in thought or statement.


  • "She loves reading books."

Period: The American Term

Conversely, in American English, the same punctuation mark is referred to as a 'period'. It serves the exact same purpose as the full stop, marking the end of a sentence.


  • "He went to the store."

Usage in Different Contexts

While the full stop and period are functionally identical, their usage can slightly vary in different contexts beyond just ending a sentence.

In Abbreviations

One notable difference in usage comes in the context of abbreviations. In American English, the term 'period' is used when referring to the dot in abbreviations.


  • "U.S.A." (United States of America)

In British English, the term 'full stop' isn't typically used in this context. Instead, the dot in abbreviations is simply referred to as a 'dot'.


  • "U.K." (United Kingdom)

In Digital Communication

In the realm of digital communication, especially in coding and online language, the term 'period' is universally used, regardless of whether British or American English is being followed.


  • "Please enter your password followed by a period."

The Dos and Don'ts of Using Full Stops and Periods

Regardless of what you call it, the rules for using this punctuation mark remain consistent.

Do: Use to Conclude Sentences

Whether you call it a full stop or a period, use it to clearly mark the end of a sentence.

Don't: Overuse in Abbreviations

In modern writing, especially in American English, the trend is to omit periods in abbreviations (e.g., "US" instead of "U.S.").
