What Is Punctuation?

Punctuation refers to the symbols used in writing to separate sentences and clarify meaning. These symbols help to indicate pauses, intonation, and the structure of sentences, making the text easier to read and understand.

Below is a list of common punctuation marks, their uses, and examples.

• She is going to the market.
• Dr. Smith will visit tomorrow.

2. Comma (,)

Use: To separate items in a list or clarify parts of a sentence.

The comma is used to separate ideas, elements in a list, or phrases within sentences. It helps to avoid confusion and add clarity.
