demonstrative

The word 'demonstrative' has a clear lineage of meaning centered on the act of pointing out. Its core originates from the Latin verb demonstrare, meaning 'to point out, show, or prove', which itself is a compound of de- (completely) and monstrare (to show). The suffix -tivus was added to form the Late Latin adjective demonstrativus, meaning 'pointing out' or 'serving for demonstration'. This term was adopted into Middle English via Old French, carrying the dual sense of providing logical proof and, later, openly indicating one's feelings. The grammatical sense, referring to words like 'this' or 'that' which point to specific things, developed directly from this foundational idea of showing or indicating.
