Punctuation is a crucial element of English writing that ensures clarity, coherence, and proper sentence structure. Whether you are preparing for the IELTS exam or improving your general writing skills, mastering punctuation can significantly enhance the readability and accuracy of your work. In this article, we will explore the most commonly used punctuation marks, their rules, and examples of correct usage.
1. The Period (.)
The period, also known as a full stop, is used to mark the end of a declarative sentence.
Usage:

- To indicate abbreviations: Dr., Mr., etc.
Common Mistake: Avoid using a period at the end of sentence fragments.

2. The Comma (,)
The comma is used to indicate a pause within a sentence, separate elements in a list, and clarify meaning.

- Before conjunctions in compound sentences: I wanted to rest, but I had to complete my assignment.

4. The Question Mark (?)
The question mark is used at the end of a direct question.
