Is a Comma Before “And” Necessary?
A comma is a punctuation mark that indicates a slight pause between different parts of a sentence. In writing, it helps readers differentiate the clauses. There are many guidelines to keep in mind when deciding whether to use a comma.

When To Use a Comma Before “And”
A conjunction is a word that connects words, phrases, and clauses to each other. And is a type of coordinating conjunction (along with for, nor, but, or, yet, and so). Another term you should be familiar with to understand when you should (or shouldn’t) use a comma before and is independent clauses. These are clauses that can stand on their own as grammatically complete sentences. When the conjunction and connects two independent clauses, then a comma is required. For example:
In the example above, the two clauses that can stand on their own are:
- Isaac went to the supermarket to buy food.
- Then he passed by his dad’s house to have dinner.
Because they can stand on their own as complete sentences, a comma should be placed before the conjunction and. Here’s another example:
However, if two independent clauses are short and closely related, then a comma before and isn’t needed. It’s a stylistic choice that’s left up to the writer.
But if and connects an independent clause to a dependent clause, then you shouldn’t add a comma.

Different publications have their own guidelines when it comes to whether a comma has to precede the conjunction and. If you’re not sure, just ask. If you’re writing for yourself, stay consistent; pick a style and stick with it.
It’s important to note that a list with only two items (or any other type of words) does not require a comma.
