Uppercase “I”

Why is “I” Always Capitalized?

English is unique in that it’s the only language that capitalizes its first-person singular, “I.” This word is derived from the German word ich. Many variations of this word flourished during Middle English, including “ic.” Eventually, the “c” was dropped, leaving “i” by its lonesome.

But why we started capitalizing “I” is a bit of a mystery. Historians and linguists have theorized the following:

A capital “I” denotes the importance of the writer.

A lowercase “I” is difficult to read.

Unless at the beginning of a sentence, me, myself, and mine don’t need to be capitalized, and neither do the rest of the personal pronouns—you, he, she, it, we, they, me, him, her, us, them.

Do Contractions With “I” Get Capitalized Too?

Contractions are shortened versions of two words. Contractions with “I” usually stand for “I 𑁋,” meaning the “I” (and only the “I”) is capitalized.

I’m (I am) going to the mall.

My brother is going, but I’ll (I will) be there.

The group is going white water river rafting, but that’s not something I’d (I would) do.

Are There Exceptions to “I” Always Being Capitalized?

No. When used as a first-person personal pronoun, “I” must always be capitalized. However, some companies use camel case for their product names. In these instances, you may find a lowercase “i”.
