determinerpronoun

Determinerpronoun is a coined term used to describe words that can function both as determiners and as pronouns, depending on context. In grammar, determiners introduce noun phrases and specify reference, number, or definiteness, while pronouns replace nouns or noun phrases. Words that can perform either role are sometimes referred to as determiner-pronouns or as a kind of polyfunctional determiner.

Common examples in English include the demonstratives this, that, these, those, which can serve as determiners before a noun (this book, those ideas) or as pronouns on their own (this is important, those are mine). Quantifiers such as some, any, all, enough can also operate as determiners (some people, all options, enough time) and as pronouns in situations like Some are late or All are invited. The word such can function as a determiner (such problems) and as a pronoun (Such is life). In each case, the form’s function is determined by its position and syntactic role.

Key distinguishing features include word order and referential function: when a determiner, the word precedes a noun; when a pronoun, it stands in place of a noun phrase and may serve as subject, object, or complement. Agreement is typically with the noun in number when used as a determiner (these books) and with the implied reference when used as a pronoun (These are mine).

Cross-linguistically, many languages have explicit separate forms for determiner and pronoun, while others reuse the same form for both functions. The notion of a determinerpronoun highlights the fluid boundary between determiner and pronoun usage in natural language, and it is primarily a descriptive label rather than a distinct grammatical category.
