* Pronouns are words that replace nouns. They don't have inherent meaning like "dog" or "tree". They get their meaning from the noun they replace.
* Examples: "he", "she", "it", "they", "this", "that"
* Common nouns are words that refer to general things, not specific individuals or places.
* Examples: "dog", "tree", "city", "mountain"
* Proper nouns are words that refer to specific people, places, or things. They are always capitalized.
* Examples: "John", "London", "Mount Everest"
So, the answer is:
* Pronouns are neither common nor proper nouns. They are a separate category of words.
* Common and proper nouns are distinct from pronouns.
It's important to remember that pronouns are essential to avoid repetition in sentences and make writing more concise.
