Key Uses of Commas
Separating items in a list:
You might be making a grocery list:
- We need eggs, milk, bread, and chapatis.
Each item is separated by a comma for clarity.
Setting off introductory Phrases or Clauses:
Let’s say you’re writing an email:
- However, I am unable to meet today.
The comma sets off the introductory adverb “However.”
Separating Independent Clauses with a Coordinating Conjunction (FANBOYS):
You’re writing a persuasive essay:
- Pollution is a major problem in Pakistan, so we need to take action.
The comma separates the two independent clauses joined by the conjunction “so,”
Non-essential Appositives:
An appositive renames or clarifies something that comes before it. For example,
- Allama Iqbal, the national poet of Pakistan, is the national poet of Pakistan”. (uses a comma to set off the appositive “)
Direct address:
You’re calling out to a friend: “Ali, come here!” The comma separates the direct address “Ali” from the rest of the sentence.
The Serial Comma (Oxford Comma) – A Special Case
This comma, used before the “and” in a list, is optional. Here’s an example:
- “I invited my parents, my brother, and my sister.” (without serial comma) vs “I invited my parents, my brother, and my sister,” (with serial comma)
While both are grammatically correct, the serial comma can add clarity, especially in lists where misinterpretations can occur key uses of commas.
