In linguistics, a '''pro-form''' is a type of function word or expression that stands in for (expresses the same content as) another word, phrase, clause or sentence where the meaning is recoverable from the context.<ref>{{cite book |last1=Crystal |first1=David |title=A dictionary of linguistics and phonetics |date=1985 |publisher=Basil Blackwell |edition=2nd}}</ref> They are used either to avoid repetitive expressions or in quantification (limiting the variables of a proposition).
Pro-forms are divided into several categories, according to which part of speech they substitute: * A pronoun substitutes a noun or a noun phrase, with or without a determiner: ''it'', ''this''. * A prop-word: ''one'', as in "the blue one" * A pro-adjective substitutes an adjective or a phrase that functions as an adjective: ''so'' as in "It is less ''so'' than we had expected." * A pro-adverb substitutes an adverb or a phrase that functions as an adverb: ''how'' or ''this way''. * A pro-verb substitutes a verb or a verb phrase: ''do'', as in: "I will go to the party if you do". * A pro-sentence substitutes an entire sentence or subsentence: ''Yes'', or ''that'' as in "''That'' is true".<ref>{{cite book|last=Rödl|first=Sebastian|title=Categories of the Temporal|year=2012|publisher=Harvard University Press|location=Cambridge, Massachusetts|isbn=978-0-674-04775-4|pages=22–25}}</ref>
An interrogative pro-form is a pro-form that denotes the (unknown) item in question and may itself fall into any of the above categories.
The rules governing allowable syntactic relations between certain pro-forms (notably personal and reflexive/reciprocal pronouns) and their antecedents have been studied in what is called binding theory.
==Table of correlatives== Some 19th-century grammars of Latin, such as Raphael Kühner's 1844 grammar,<ref>{{cite book |last1=Kühner |first1=Raphael |title=Elementargrammatik der lateinischen Sprache mit eingereihten lateinischen und deutschen Übersetzungsaufgaben und einer Sammlung lateinischer Lesestücke nebst den dazu gehörigen Wörterverzeichnissen |date=1844 |page=35 |url=https://books.google.com/books?id=kwU1AQAAMAAJ&dq=kuhner+Grammatik&pg=PA35 |access-date=2022-12-02}}</ref> organized non-personal pronouns (interrogative, demonstrative, indefinite/quantifier, relative) in a table of "correlative" pronouns due to their similarities in morphological derivation and their syntactic relationships (as correlative pairs) in that language. Later that century, L. L. Zamenhof, the inventor of Esperanto, made use of the concept to systematically create the pro-forms and determiners of Esperanto in a regular ''table of correlatives''. The table of correlatives for English follows.

Some languages may have more categories. See demonstrative.
Note that some categories are regular and some are not. They may be regular or irregular also depending on languages. The following chart shows comparison between English, French (irregular) and Japanese (regular):
{| class="wikitable" style="white-space: nowrap" |- ! rowspan="2" | ! rowspan="2" | interrogative ! colspan="2" | quantifier |- ! existential !! negative |- ! human | who<br>qui<br>dare | someone<br>quelqu'un<br>dareka | no one<br>(neg. +) personne<br>daremo + neg. |- ! nonhuman | what<br>que<br>nani | something<br>quelque chose<br>nanika | nothing<br>rien<br>nanimo + neg. |- ! location | where<br>où<br>doko | somewhere<br>quelque part<br>dokoka | nowhere<br>nulle part<br>dokomo + neg. |}
(Note that "daremo", "nanimo" and "dokomo" are universal quantifiers with positive verbs.)
Some languages do not distinguish interrogative and indefinite pro-forms. In Mandarin, "''Shéi'' yǒu wèntí?" means either "''Who'' has a question?" or "Does ''anyone'' have a question?", depending on context.
