|2. Comma (,)|
A comma is used in the middle of, and never at the end of a sentence. This is done to make the sentence clearer, especially to separate items in a list. However, overusing commas can complicate a sentence, or render it meaningless. A comma is important to avoid any possibility of misunderstanding a sentence as the following example shows:
While my father was eating, my mother was drinking.
A comma is used:
EXAMPLE: We saw monkeys, porcupines, lions and tigers in the zoo.
EXAMPLE: Yesterday, as I was jogging in the park, I saw a black baboon.
EXAMPLE: He told us, "I believe the world is flat."
EXAMPLE: "Jane, let me show you how to do it."
EXAMPLE: He is marrying on Tuesday, 1st April.
EXAMPLE: Oh no, it can't be true.
EXAMPLE: Of course, you are always right.
