We will study how to use commas (,) in this lesson. Let's look at the different ways that we use commas when we write in English.

1. Separate clauses

• I like it, but she doesn't like it.
• Since it is cold, I will not go out.
• She has a good heart, and she is funny.
• Unless I am sick, I will attend the show.

2. Separate words in a list

• I like pizza, hamburgers, and cookies.
• She visited Slovenia, Poland, and Ukraine.
• We can have Indian, Chinese, or Thai food.

3. Separate non-restrictive appositive nouns

• My friend, Bob, will come with us.
• She talked to her boss, Tony.
• Buddy, my dog, is sick.

Punctuation is essential for writing in English. Punctuation helps you express your thoughts, feelings, and ideas in a way that is easy for the reader to understand.
