In this ESL writing worksheet, students are introduced to the proper usage of the conjunction “and” with both dependent and independent clauses.
Punctuation: Commas and Conjunctions (with “and”)
When you write “and” in a sentence, you have to be careful: Do you need a comma?
Look at these sentences:
-
- · I went to the theater. I watched a movie.
These are both complete sentences, so you can connect them with a comma (,) and “and”:
-
- · I went to the theater, and I watched a movie.
But you can also write this a different way:
-
- · I went to the theater and watched a movie.
You do not need a comma in this sentence, because “watched a movie” is not a complete sentence (it doesn’t have the subject “I”).
Examples (all of these sentences are correct!):
-
- · John ate a sandwich, and he watched TV.
- · John ate a sandwich and watched TV.
- · Martha visited her daughter, and she had a good time.
- · Martha visited her daughter and had a good time.
