Pronoun usage refers to the grammatical patterns governing the selection, form, and interpretation of pronouns within linguistic structures. It concerns how pronouns function as nominal expressions that substitute for or refer to entities, participants, or discourse elements, and how their grammatical properties, including person, number, gender, case, and reference, interact with syntactic and semantic relationships ^[1]. Pronoun usage is distinguished from the broader category of pronoun systems, which describes the inventory and classification of pronoun forms in a language, by focusing specifically on the conditions and principles that regulate pronoun selection and interpretation in particular linguistic contexts ^[2].
