👉 In linguistics, the term "nominator" refers to a noun that is used as the subject of a sentence. It is also called the "subject pronoun." Nominative forms are those in which the subject begins with the prefix "-s-" (e.g., "I am going to the store"), and they indicate who or what the subject is addressing, usually referring to a person, place, thing, or idea. For example: 1. I am writing this letter. 2
