A matchless woman? (8)
I believe the answer is:
spinster
'a matchless woman?' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
This is the entire clue.
Can you help me to learn more?
(Other definitions for spinster that I've seen before include "One spurning union activity" , "old maid, perhaps" , "matchless female" , "Single woman" , "Unmarried older woman" .)
