It helps convey meaning effectively, ensuring that the writer's intentions are understood by the reader. Proper use of punctuation marks can significantly alter the interpretation of a sentence, highlighting its importance in written expressions.

Lynne Truss, in her book "Eats, Shoots & Leaves: The Zero Tolerance Approach to Punctuation," emphasizes the role of punctuation in maintaining clarity in writing. By adhering to proper punctuation rules, writers can enhance their message and avoid misunderstandings, reflecting the interconnectedness of punctuation and clear thinking.
