The comma is one of the most important punctuation marks in English. Knowing how to use it properly is essential for every ESL student.
1. Use commas before co-ordinating conjunctions that join independent clauses.
- I gave him a severe punishment, but it didn't help at all.
2. Use commas after introductory phrases and adverb clauses.
- After he had humiliated himself in front of the jury, he gave up singing for good.
3. Use commas to seperate things in a series:
- We went to the shop and bought a lot of products: vegetables, fruits, sweets and spices.
4. Use commas to set off non-restrictive elements and other parenthetical elements.
- This restaurant, that I discovered last week, serves exellent wine.
