Punctuation

Punctuation is a fundamental aspect of writing that plays a crucial role in conveying meaning and clarity in the English language. By using various punctuation marks, writers can structure their sentences, organize their thoughts, and emphasize important points. Without punctuation, written communication would be ambiguous and challenging to understand.
