7 Tips on How to Use Commas in English
1. The seven coordinating conjunctions: and, but, for, or, nor, so, yet demand a comma to separate an independent clause. Example:
“He climbed to the top of the mountain, but he still couldn’t see the sea.”
2. When we put an introductory phrase before a main clause, we use a comma. Example:
“Early one morning, Mariadecided to climb Everest.”
3. When we want to add extra (non-essential) information in the middle of a sentence, we use commas to separate this idea from the main sentence.
Maria, who had never climbed a mountain before, decided she would like to climb Everest.”
4. We use commas to separate three or more words, phrases, or clauses written in a series.
“Maria packed a rope, a tent and a compass for the trip”
5. We use a comma to separate adjectives describing the same noun.
“She took a big, old, red tent with her.”
6. We use a comma near the end of a sentence to separate a contrasting part of the sentence. This is usually used to reflect spoken English. Example:
“You haven’t ever climbed a mountain before, have you?”
7. We use a comma to shift between the main sentence and a quotation.
She looked at the sherpa and said, “Can you please show me the way?”
