demonstrate
UK: /ˈdɛmənstreɪt/ | US: /ˈdɛmənstreɪt/
vt. to show or prove something clearly
vt. to explain or teach by practical examples
vi. to participate in a public protest or rally
The word "demonstrate" traces back to Latin demonstrare, combining de- (emphasizing completeness) and monstrare (to show). Originally, it meant "to point out clearly" or "to prove logically." Over time, it expanded to include teaching through examples (16th century) and later public displays of protest (19th century). The morpheme strate subtly reflects the idea of "laying out" evidence or actions visibly.
