Control comes with financial gift — main way to get in (10)
I believe the answer is:
domination
'control' is the definition.
(I know that domination is a type of control)
'with financial gift main way to get in' is the wordplay.
I cannot quite see how this works, but
an anagram of 'main' is 'mina' which is located in the answer.
'way' could be 'n' (Compass direction - North) and 'n' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'comes' is the link.
Can you help me to learn more?
(Other definitions for domination that I've seen before include "Controlling influence" , "rule" , "Absolute authority" , "Command, power" .)
