What is a first person nominative singular pronoun?

Question

Will someone giveme definitionand an example?

Answer 1

I

As in "I hate grammar."  

Answer 2

These are terms taken from Latin to teach English grammar. It's not very effective anymore because people don't know the labels.

The answer is: I (as in "I am happy today.")

First person = "I" or "we" because we speak of ourselves (first persons) in this way.

Singular = "I" and not "We" (because "we" is always more than one).

Nominative pronouns = "I" or "we"

Accusative pronouns = "me" or "us" (which is not what your question is asking).

Good luck figuring out English grammar.
