Etymology
The word 'nonlabeled' is a modern English compound formed by applying the productive negative prefix 'non-' to the past participle 'labeled'. The prefix 'non-' derives from Latin 'non', a straightforward adverb of negation. The root 'label' entered English from Old French, where it originally referred to a ribbon or strip of cloth, a sense which evolved to mean an attached slip for identification. The suffix '-ed' is a native English participial ending. The logical construction is transparent: 'not' + 'having been provided with a label', resulting in the contemporary meaning of lacking an identifying tag.
