poorly
UK: ˈpɔːli | US: ˈpʊrli
adv. in an inadequate or unsatisfactory manner
adj. (chiefly British) unwell or in poor health
The word "poorly" combines "poor," derived from Old French "povre" (Latin "pauper," meaning "lacking wealth or quality"), with the adverbial suffix "-ly," originating from Old English "-līce." The suffix transforms adjectives into adverbs, indicating manner or state. Over time, "poorly" evolved to describe both inadequate performance ("done poorly") and physical health ("feeling poorly"), the latter being a British colloquialism.
The project was poorly managed, leading to delays.
She sang poorly during the audition due to nervousness.
He’s been feeling poorly since yesterday.
The instructions were written poorly, confusing everyone.
The machine functions poorly in extreme temperatures.
