inflatable
UK: ɪnˈfleɪtəbl | US: ɪnˈfleɪtəbl
adj. capable of being filled with air or gas
n. an object designed to be filled with air or gas
The word "inflatable" derives from the Latin root flare (to blow), which evolved into flat- in English (as seen in "inflate"). The prefix in- (into) combines with flat- to form "inflate," meaning "to blow into." The suffix -able (capable of) was added later to create the adjective "inflatable," describing objects designed to be filled with air. This logical progression reflects the word's functional purpose—highlighting its ability to expand when air is introduced.
