expand
UK: ɪkˈspænd | US: ɪkˈspænd
v. to increase in size, volume, or scope
v. to express something in fuller form (e.g., ideas)
v. (physics) to spread out (e.g., gases)
Derived from Latin expandere ("to spread out"), combining ex- (outward) and pandere (to spread, extend). The root pandere also appears in words like "pandemonium" (literally "place of all demons," implying chaotic spreading). Over time, "expand" evolved from physical spreading (e.g., expanding a map) to abstract growth (e.g., expanding knowledge).
