unexceptionable
UK: ˌʌnɪkˈsɛpʃənəbl | US: ˌʌnɪkˈsɛpʃənəbl
adj. beyond criticism or objection; entirely satisfactory
The word combines the negative prefix "un-" (from Old English "un-," meaning "not") with "exception" (from Latin "exceptio," meaning "objection" or "exclusion") and the suffix "-able" (from Latin "-abilis," indicating capability). Originally, "exceptionable" meant "open to objection," but adding "un-" flips the meaning to "not open to objection" or "flawless." The term reflects a logical progression from "objectionable" to its opposite through negation.
