Raise fees for it, if you think appropriate (3,3)
I believe the answer is:
see fit
'you think appropriate' is the definition.
I can't judge whether this defines the answer.
'raise fees for it' is the wordplay.
'raise' says the letters should be written in reverse.
'for' says to put letters next to each other.
'fees' back-to-front is 'seef'.
'seef'+'it'='SEE FIT'
'if' is the link.
Can you help me to learn more?
(Other definitions for see fit that I've seen before include "Perceive in good shape, so choose to do?" , "Consider appropriate, decide to do" , "Consider appropriate or choose to do" , "Think suitable" , "Want" .)
