Punctuation refers to symbols used to clarify meaning, structure, and pauses in writing. Examples include commas, periods, question marks, exclamation points, etc.
Capital letters are used to:
* Start sentences: This helps us identify where a new thought begins.
* Mark proper nouns: This includes names of people, places, and organizations.
* Show emphasis: This is done by capitalizing specific words or phrases.
While capital letters play a crucial role in grammar and clarity, their function is distinct from punctuation.
