demonstrative

adj. expressive, demonstrating emotions or opinions; serving to explain or illustrate

Demonstratives are deictic words (they depend on an external frame of reference) that indicate which entities a speaker refers to, and distinguishes those entities from others. Demonstratives are usually employed for spatial deixis (using the context of the physical surroundings), but in many languages they double as discourse deictics, referring not to concrete objects but to words, phrases and propositions mentioned in speech.
