Important things to consider while correcting punctuation!

Here are some key punctuation rules to keep in mind when correcting punctuation:

Commas

It’s good to use commas to separate items in a list: I bought apples, oranges, bananas, and grapes.

It is helpful to place a comma after introductory words or phrases: After lunch, we went for a walk.

It’s important to use commas between clauses in compound sentences: I wanted to go swimming, but it started raining.

Periods

Always place a period at the end of declarative sentences: She enjoys reading books.

It’s good to use periods for abbreviations: Mr., Dr., etc.

Apostrophes

It is important to use apostrophes to show possession: Sarah's book is on the table.

For plural possession, it’s correct to add an apostrophe after the "s": The teachers' lounge is closed.

Never use apostrophes for plurals: The books are on the shelf (not The book's are on the shelf).

Quotation Marks

It’s good to use quotation marks to enclose direct speech or quotations: "I love ice cream," she said.

Remember, punctuation marks like commas and periods go inside the quotation marks: "It's a beautiful day," he said.

Semicolons

It’s helpful to use a semicolon to join closely related independent clauses: I went to the store; I forgot to buy milk.

Use semicolons to separate items in a complex list: We visited Paris, France; Rome, Italy; and Madrid, Spain.

Colons

It’s good to use a colon to introduce a list or explanation: She bought three items: milk, bread, and eggs.

You should use a colon after a salutation in formal letters: Dear Sir or Madam:

Question Marks

It’s important to place a question mark at the end of a direct question: How are you today?

Do not use a question mark for indirect questions: He asked how you were.

Exclamation Marks

It’s helpful to use an exclamation mark to show strong emotion or excitement: What a beautiful sunset!

Avoid using too many exclamation marks in formal writing.

Parentheses

It’s useful to use parentheses to add extra information or clarification: She finally answered the phone (after three missed calls).

Keep punctuation outside the parentheses unchanged: He went to the store (which was closed) and left immediately.

Hyphens

It’s good to use hyphens for compound words like mother-in-law or well-known.

You should use hyphens for numbers like twenty-three or fifty-five.
