'unmarried woman' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?

'plays with hair' is the wordplay.
'plays' becomes 'spins' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'with' is a charade indicator (letters next to each other).
'hair' becomes 'tress' (tress is a kind of hair).
'spins'+'tress'='SPINSTRESS'
