unspecified
UK: ʌnˈspesɪfaɪd | US: ʌnˈspesɪfaɪd
adj. not stated clearly or exactly; lacking specific details
The word "unspecified" combines the negative prefix "un-" (from Old English "un-," meaning "not") with the verb "specify" (from Latin "specificare," meaning "to state clearly," derived from "species" [kind] + "facere" [to make]). The suffix "-ed" turns it into an adjective. The term evolved to describe something that has not been clearly defined or detailed, retaining the logical negation of "specified."
