Impotence of father visiting Cuzco perhaps (10)
I believe the answer is:
incapacity
'impotence' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'father visiting cuzco perhaps' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'visiting' means one lot of letters goes inside another.
'cuzco perhaps' becomes 'Inca city' (Cuzco was a city of the Inca Empire).
'pa' placed into 'incacity' is 'INCAPACITY'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for incapacity that I've seen before include "Lack of required skills" , "Disability" , "Lack of authority" , "Helplessness" , "Lack of power or ability" .)
