Definition & Meaning of "nominative case"

What is the "nominative case"?

The nominative case is a grammatical category used primarily to indicate the subject of a sentence or clause. In English, the nominative case includes pronouns such as "I," "he," "she," "we," and "they," which function as the subject performing the action of the verb. For example, in the sentence "She runs fast," "she" is in the nominative case because it is the subject doing the running. The nominative case is essential for identifying who or what is carrying out the action in a sentence, helping to clarify the structure and meaning of statements.
