Punctuation is the practice of using certain characters in writing to separate words and make the meaning clear. There are different rules for proper punctuation in the English language.
Punctuating Items in a Series:
Use a comma after each item in a series of at least three items. The comma before the “and” is optional.
Example: I still need to take a shower, make my bed, and eat breakfast.
Use a comma before etc.
Example: Dad went to the store to get apples, pears, oranges, grapes, etc.
Use a colon before a list that comes after an independent clause.
Example: You need to ask the following people to sign the card: Carrie, Sarah, Tiesha, and Shaghit.
