Modern English ultimately derives from Old English, which is a Germanic language. This is the language spoken in Britain before the Norman invasion of 1066.

In German, all nouns are capitalized.

In German, Ich is the word for I and it is capitalized.

German words for “me,” to me,” “mine,” are not capitalized.

For instance, Ich, meiner, mir, mich.

The English language is not logical, but it does reflect a rich history of primarily German, French, and Latin influences. Thus tradition and precedent is your answer, not logic.

But what I would say is that “I” has capital because it is referring to yourself and is the equivalent of someone saying you name which would be written with a capital letter. My doesn’t have a capital unless at a beginning of a sentence because it referring to something that belongs to you rather than actual person.

And me………. well i have no explanation for that one lol

The English language is mixed up and they decided to make that a rule. To tell you the truth i think there IS a reason why to this but i just don’t know it… sorry

“I” is also capitalized because it describes the speaker – it’s just one of those lovely things about the English language 🙂
