Question

Is "I" a proper noun? Why is it always capitalized when "he" and "she" are not?

Answer 1

A proper noun is the name given to something to make it more specific (e.g., Johnathan, Ollie, London, Monday). Proper nouns are written with capital letters regardless of where they appear in a sentence. Proper nouns contrast with common nouns, which are the words for something (e.g., boy, dog, city, day).

Answer 2

I is not a proper noun it's a pronoun but he , she are proper noun so it should not be capitalized .the when any places ,thing are specifed it should be capitalized
