Nominative - The category of nouns serving as the grammatical subject of a verb.

Subjective - Relating to or being the nominative case.

The nominative case pronoun expresses a subject, expresses a repeated subject, expresses the subject when the verb is omitted or comes after the verb. The pronouns I, we, you, it, he, she, they, who or whoever indicate the nominative case.

To express a subject you would say: Bob and I read the book. “I” is the nominative pronoun. You would not say: Bob and me read the book.

I know who read the book. “Who” is the subject of “read”.

With repeated structure you say: We read the book - Bob, Sue and I. Again, you don’t use the word “me”.

To express the subject without the verb you say: He is faster than she. this is correct even though the verb “is” has been ommitted from the end of the sentence.

After verbs you’ll often see an objective used instead of the nominative pronoun: I wouldn’t want to be him. “Him” is objective instead of the word “he” which would be the nominative pronoun.
