unprofitable
UK: ʌnˈprɒfɪtəbl | US: ʌnˈprɑːfɪtəbl
adj. not yielding profit or financial gain
adj. (figuratively) not beneficial or worthwhile
unprofitable = un<not> + profit<gain> + able<capable of>
- un (prefix): From Old English "un-," meaning "not" or "opposite of."
 - profit (root): From Latin "proficere" (to make progress, gain), via Old French "profit" (advantage, benefit).
 - able (suffix): From Latin "-abilis," indicating capacity or suitability.
 
Etymology Origin:
The word "unprofitable" combines negation ("un-") with "profit," rooted in the Latin idea of advancement or gain. The suffix "-able" transforms it into an adjective meaning "incapable of yielding profit." Historically, "profit" shifted from general "benefit" to specifically financial gain in Middle English, while "un-" consistently negates the root's meaning.
