Etymology

The word "unwell" is a straightforward English compound formed by adding the native negative prefix "un-" to the adjective "well". The prefix "un-" descends from the Proto-Germanic un-, which itself originates from the Proto-Indo-European n̥-, a common negative particle. The adjective "well", meaning in good health, evolved from Old English wella, an adjectival use related to the adverb wel, meaning "in a good way" or "prosperously". Therefore, the literal construction "not well" has remained semantically transparent from its Old English roots to its modern usage, directly describing a state of being not in good health.
