If the word i capitalized is it a spelling error?

Yes, "i" should not be capitalized unless it is the first word of a sentence or part of a proper noun.

Here's why:

* It's a personal pronoun: "I" refers to the speaker, and personal pronouns are generally lowercase.

* Proper nouns are capitalized: If "i" is part of a name, like "I-40" (a highway) or "I.M. Pei" (an architect), then it should be capitalized.
