“Demonstrative Pronoun: A pronoun that shows where something is in relation to the speaker and listener. Standard English has four demonstratives, paired and with number contrast; this/these here, that/those there. Some dialects have three (this, that, yon/yonder) and Scots has this, that, yon/yonder and its variant thon/thonder. The set of three are comparable to Latin hic this near me, iste, that near you, ille that over there. For some grammarians, the term covers the demonstratives however used; for others, demonstrative pronouns (‘I like that,’ Give me some of these’) are distinguished from demonstrative determiners (‘I like that one,’ ‘Who are these people?’).”
