When trained, can bring in excellent money (7)
I believe the answer is:
finance
'when trained can' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'in excellent money' is the wordplay.
'in' is an insertion indicator.
'excellent' becomes 'fine' ('fine' can be a synonym of 'excellent').
'money' becomes 'anc' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'fine' placed around 'anc' is 'FINANCE'.
'bring' acts as a link.
Can you help me to learn more?
(Other definitions for finance that I've seen before include "Provide capital" , "Provide funds for" , "Supply funds" , "Support monetarily" , "Provide cash for" .)
