When to Add a Comma Between Two Adjectives

You should add a comma between two adjectives when they can be reordered. We avoid the use of comma if the adjectives cannot be rearranged.

Do You Need a Comma Before 'But'?

If the clause after "but" has a subject and a verb, you need a comma before but. If the clause introduced by "but" does not have a subject in front of the second verb, the comma is often optional.

When to Add a Comma Before 'AND'

When there are two items in a list, you should not use a comma before and. If the list has three or more items, the use of comma is optiona.

How to Use Commas Correctly with 'Who', 'Which', and 'That'.

1) Do not place a comma before "that"; 2) Do not place a comma before who or which if the information provided by the relative clause is essential; 3) Place a comma before who or which if the relative clause is not necessary to know who or what the speaker means.

Repeating the Subject After 'But'?

You don't need to repeat the subject after "but" if both parts of your sentence (clauses) have the same subject. Therefore, you can mention it again or omit it in the second clause.

Subject After 'Because'. Do I Have to Repeat It?

Because must be followed by a subject and a verb. Therefore, if the subject of both clauses is the same, we have to repeat the subject or the subject pronoun after "because".
