A professional dancer (6)
I believe the answer is:
gigolo
This clue might be a double definition.
'a professional' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'dancer' is the second definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
Can you help me to learn more?
(Other definitions for gigolo that I've seen before include "Man paid by older woman to be her lover" , "Old word for man maintained by rich woman" , "Paid male lover" , "Professional male escort" , "Kept man" .)
