    English underuses it

You mean it underuses capitalization? What are the examples in other languages that uses for other purposes?

[doctor_eval]

I believe that in German all Nouns are Capitalised, not just Proper Nouns.

Please correct Me if I’m wrong.

(Except for my Capitalisation, which is all over the place because I’m trying to illustrate to English readers why I find German really hard to read)

[giomasce]

Notice that "Capitalised" and "Proper" are adjectives and "Me" is a pronoun, so they're not capitalised in German.

[wanderingstan]

Yes, that is correct.

It’s just a convention. Early English writing sometimes also capitalized all nouns.

I imagine the capitalization of Latin alphabets must seem crazy to someone whose native language doesn’t have them.
