Punctuation: A Quick Guide

What is Period Punctuation?

Period punctuation is a tiny dot structure (.) that is usually put at the end of a declarative sentence to show its ending. It occurs at the bottom side of the sentence and is also known as a full stop in British English. The Period mark follows the previous character without having a space after it. Moreover, there is a definitive break that is carried by these marks which is more noticeable than other punctuation marks within any sentence.  

Mr. Miller lives at the house next to me.
He lives in “341 Tentbrooke Ave.” 

When to Use Period Punctuation? 

There are mainly two purposes that period punctuation marks serve –

  • The main purpose of the full stop is to show that the sentence has been concluded. The period is the third punctuation mark that ends the sentence along with the exclamation mark (!) and question marks (?). It can only be used to put the end of commands such as imperative or declarative sentences.

For Example: 

The grass is green.
Wash the spoons before you use them.
  • The Period punctuation is used to indicate that some information such as a few letters has been removed from the sentence. Additionally, they are also used in abbreviations such as i.e., e.g., et al, etc., and c. Periods are sometimes used at the beginning of a sentence when only the first letter of the name or the word is present. 

For Example: 

They brought a pen, pencil, eraser, etc. for the competition.
W.G. Grace is known as the Father of Cricket.
