Came back, briefly, to get man's doctor to demonstrate virility and strength? (8)
I believe the answer is:
machismo
'strength?' is the definition.
(I've seen this before)
'came back briefly to get man's doctor to demonstrate virility' is the wordplay.
I cannot quite see how this works, but
'man's' could be 'his' (belonging to a man) and 'his' is present in the answer.
'doctor' could be 'mo' (medical officer) and 'mo' is found in the answer.
The remaining letters 'mac' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for machismo that I've seen before include "form of pride" , "A show of virility or manliness" , "virile obsession" , "Cult of virility" , "show of masculinity" .)
