Punctuation Rules
Punctuation marks clarify meaning and structure in written language.
Comma (,)
- Separate items in a list: apples, oranges, and bananas
- After an introductory clause or phrase: After the exam, she slept.
- Before a coordinating conjunction (FANBOYS) joining two independent clauses.
- Example: She studied hard, and she passed.
Semicolon (;)
- Joins two closely related independent clauses that are not connected by a coordinating conjunction.
- Example: She studied hard; she passed the exam.
- Separates items in a complex list where items themselves contain commas.
Colon (:)
- Introduces a list, explanation, or example after an independent clause.
- Example: He had one goal: to pass CMAT.
- Between two independent clauses when the second clause explains or illustrates the first.
Apostrophe (')
- Indicates possession: Ram's book, students' books
- Indicates contraction: it's (it is) = it is (≠ its = possessive of it)
- Correct Example
- She bought apples**,** oranges**,** and bananas.
- He was exhausted**;** however, he continued.
- Remember one thing**:** practice every day.
- Incorrect Example
Its a good idea.(The contraction 'it is' needs an apostrophe: It's)The student's are absent.('Students' is a plural subject here, not possessive, so no apostrophe is needed)
