| Definition -
A pronoun that designates or points out.
1. English has four of them: this, that, these, and those. However, many feel that three more should be added to the list:
(1) such (as in "Such were the joys"),
(2) yonder (as in "Yonder stands the tallest tree"), and
(3) yon (as in "Yon tree is huge").
Example - This bud's for you.
Oxford English Dictionary - The term's first citation is from 1591:
"Of pronounes … some are called demonstratiues, because they shew a thing not spoken of before."
(Percivall Sp. Dict. Biva)
