‘He’ is considered a pronoun, specifically a personal pronoun, rather than a common or proper noun. Common nouns refer to general items, places, or people (like ‘dog’, ‘city’, or ‘teacher’), while proper nouns name specific entities (like ‘Rover’, ‘New York’, or ‘Mr. Smith’).
Pronouns like ‘he’, ‘she’, or ‘they’ are used to replace nouns in sentences to avoid repetition. In summary, ‘he’ does not fit into either the common or proper noun categories, as it serves a different grammatical purpose.
