Common Punctuation Mistakes
-
Comma splice: Combine two independent clauses with a comma without a coordinating conjunction (and, but, or, nor, yet, so, for, etc.). Instead, use a semicolon, coordinate conjunction, or rewrite the sentence to prevent the error.
Incorrect: I went to the store. I bought bread.
Correct: I went to the store; I bought bread.
OR
Incorrect: I studied hard for my exam. I aced it!
Correct: I studied hard for my exam, and I aced it!
OR
Incorrect: I studied hard for my exam. Aced it!
Correct: I studied hard for my exam. I aced it!
-
Serial (Oxford) comma: When listing items with a coordinating conjunction, use a comma before the conjunction and after the last item. This is known as the serial comma or the Oxford comma.
Incorrect: Apples, bananas, grapes.
Correct: Apples, bananas, and grapes.
Types of Punctuation Marks
Apostrophe
The apostrophe indicates possession or contraction. For singular nouns, use the apostrophe + s; for plural nouns ending in s, use apostrophe alone; for plurals not ending in s, add s + apostrophe.
Example:
- Singular noun: John's book
- Plural noun ending in s: The dogs' toys
- Plural noun not ending in s: The children's laughter
Ellipsis
Used to indicate an omission of words in a sentence or to show trailing off at the end of a sentence.
Example:
- Omission: He said, "Hello," ... and waved goodbye.
- Trailing off: She forgot her keys ... again.
Period
Indicates the end of a declarative sentence.
Example:
- Declarative sentence: The cat is sleeping.
Dash
Two types of dashes: en dash and em dash. En dashes are equal in width to the letter n, while em dashes are equivalent to the letter m. Both dashes can be used to indicate a break within a sentence or to separate elements.
Example:
- En dash: The bookstore was opened in 1980 – 2008.
- Em dash: My dad is finally retiring — but he'll be a tough act to follow.
Hyphen
Connects compound words or two-word adjectives.
Example:
- Compound word: Mother-in-law
- Two-word adjective: Long-term memory
