unnecessary
UK: ʌnˈnɛsəs(ə)ri | US: ʌnˈnɛsəˌsɛri
adj. not needed or required; superfluous
adj. excessive or redundant
The word "unnecessary" combines the Old English prefix "un-" (meaning "not") with "necessary," which derives from Latin "necessarius" (indispensable, inevitable). "Necessary" itself comes from "ne-" (not) + "cedere" (to yield), suggesting something that cannot be avoided. By adding "un-," the word flips the meaning to imply something avoidable or excessive. This logical negation reflects a straightforward but powerful evolution in English word formation.
