Morphology

unpaired = paired (transparent) = un + pair + ed

Formed by adding the negative prefix 'un-' to the adjective 'paired'; meaning 'not matched' is directly derivable.

Etymology

Unpaired comes from the prefix un- meaning 'not' and the word pair meaning 'two that go together', like a pair of shoes. So unpaired means 'not with its partner', the single item left when the other is missing.
