A demonstrative is a deictic proform whose deictic features do not reduce to identification of a speech-act participant.

This definition embraces a set of alternatives:

The subcategories are illustrated by the following examples:

The German dér is a third person demonstrative contrasting with the third person pronoun er ‘he’.

In many languages, the same demonstrative forms serve as pronouns and as determiners. Thus, Latin hic - iste - ille ‘this (one) - that (one) near you - yonder (one)’.

There are also demonstrative copulas (Diessel 1997) and demonstrative verbs (Juǀ’hoan hè ~ kè ‘be PROXIMAL’ vs. tö'à ‘be DISTAL’; Lionnet 2013).
