Punctuation Marks and Their Usage:
Period (.)
- Ends declarative and imperative sentences: "The cat is asleep."
- Used after abbreviations: "Dr.", "Mr."
- Avoid using periods unnecessarily, such as after titles or headings.
Exclamation Mark (!)
- Indicates strong emotion or emphasis: "This is amazing!"
- Avoid overusing exclamation marks, as it can weaken their impact.
Question Mark (?)
- Ends interrogative sentences: "Are you okay?"
- Enclosed within quotation marks if the question mark is part of the quoted material: "She asked, 'What time is it?'"
Comma (,)
- Separates items in a list: "apples, oranges, bananas"
- Connects two independent clauses if a coordinating conjunction (and, but, or, nor, for, so, yet) is used: "I went to the store, but I didn't find what I needed."
- Separates introductory elements from the rest of the sentence: "To be honest, I'm not sure."
Semicolon (;)
- Separates two closely related independent clauses that are not joined by a coordinating conjunction: "The book was interesting; it held my attention throughout."
- Can also be used to separate items in a list that already contain commas: "The ingredients include apples, oranges; bananas, strawberries; and pineapple."
Colon (:)
- Introduces a list: "The ingredients are as follows:"
- Introduces a formal quotation: "He said: 'I will not be attending.'"
- Separates hours and minutes in time: "4:30 PM"
Apostrophe (')
- Indicates possession: "the cat's tail"
- Forms contractions (shortened forms) of words: "don't", "can't"
Single and Double Quotation Marks
- Enclose direct quotations: "She said, 'I'm going for a walk.'"
- Single quotation marks are used within double quotation marks to enclose a quotation within a quotation: "She quoted the famous line, 'To be or not to be.'"
Hyphen (-)
- Joins compound words: "ice-cream"
- Indicates a range of numbers or values: "1990-2000"
- Avoid using hyphens to connect words that do not form a compound word (e.g., "highly recommended")
Confusion and Ways to Avoid It:
- Apostrophes in plural possessive forms: Do not add an apostrophe before the "s" in regular plural possessive forms (e.g., "the students' books").
- Commas in non-restrictive clauses: Restrictive clauses (which provide essential information) do not require commas, while non-restrictive clauses (which provide additional information) do (e.g., "The students who work hard, will succeed.").
- Hyphens vs. dashes: Hyphens connect words or parts of words, while dashes (em dashes, used as —) indicate a sudden break or change in thought.
