Should “I” be capitalized or in lower case? [duplicate]

Solution 1:

One of the capitalization rules is, to capitalize the letter "I" when referring to yourself, so it must be capitalized:

In English, the nominative form of the singular first-person pronoun, "I", is normally capitalized, along with all its contractions (I'll, I'm, etc.).

So, it would be:

2) Now I want to leave for home.

as well as:

I'm leaving for home.

N.B. Only "i" when used as a pronoun is capitalized.

Solution 2:

The pronoun form of I should be capitalized in all cases where it stands alone. However, a word beginning with that letter follows normal capitalization rules.
