Show mounting ability to do well? (3,2)
I believe the answer is:
get on
'do well?' is the definition.
(thesaurus)
'show mounting ability to' is the wordplay.
I cannot quite see how this works, but
'to' is within the answer.
The remaining letters 'gen' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for get on that I've seen before include "Make progress or mount up" , "fare" , "What boarders do" , "Board - prosper" , "Make progress, do well in life" .)
