Definition of Punctuation

Punctuation is the system of symbols used in writing to separate sentences and clarify meaning. It helps readers understand the structure and flow of the text by indicating pauses, stops, or emphasis.

For example:

• Let's eat, Grandpa! (with punctuation – means calling Grandpa to eat)
• Let's eat Grandpa! (without proper punctuation – sounds like eating Grandpa!)

---

1. To Introduce a List

Use a colon after a complete sentence to introduce items in a list.

Examples:

1. You need to bring the following: a pen, a notebook, and a calculator.

Uses of Dash ( — ) in English

A dash (—) is a punctuation mark used to create emphasis, add extra information, or show a sudden break in thought. It is longer than a hyphen (-) and should not be confused with it.

There are two main types:

• Em dash (—): Commonly used in writing (long dash).
• En dash (–): Used for ranges (e.g., 2010–2020).

Below are the main uses of the em dash (—):

---

2. He got what he deserved — a second chance.

---

5. To Indicate Interrupted Dialogue (in Stories or Scripts)

Used to show that a character is cut off or interrupted.

Uses of Hyphen ( - ) in English

A hyphen (-) is a short punctuation mark used to join words or split words at the end of a line. It is not the same as a dash (—), which is longer.

---

1. To Form Compound Words

Hyphens are used to connect two or more words that act as a single idea (compound adjectives or compound nouns).

Examples:

• My father-in-law is visiting.
• She bought a well-known brand.
• He is a full-time employee.

---

2. To Avoid Confusion or Misreading

A hyphen helps clarify the meaning of certain combinations of words.

Examples:

• Re-sign (sign again) vs. Resign (quit a job)
• Co-op (cooperative) vs. Coop (chicken house)

---

3. With Prefixes and Suffixes

Some words with prefixes or suffixes need a hyphen, especially when:

• The root word is capitalized.
• There’s a repetition of the same vowel.
• To avoid ambiguity.

Examples:

• ex-president
• re-enter
• anti-American
• self-esteem

---

4. To Indicate Word Division at the End of a Line

In writing, a hyphen can split a word that doesn’t fit on one line (less common in digital writing now).

Example:

• The children were enjoy-
  ing their summer vacation.

---

5. In Numbers and Fractions (as adjectives)

Used in number words or when fractions are used as adjectives.

• A two-thirds majority is required.

5. In Questions within Quotations

If a quoted sentence is a question, the question mark goes inside the quotation marks.

Examples:

1. She asked, “Are you okay?”
2. He said, “What are we waiting for?”

6. In Questions within a Sentence

When the question is embedded in a longer sentence, only the question part gets the question mark.
