Change be enough? Bankers to count on the other hand (6)
I believe the answer is:
doctor
'change' is the definition.
(doctoring is a kind of changing)
'on the other hand' is the wordplay.
'on' means one lot of letters goes inside another (as in clothing 'on' a person).
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'other' becomes 'doco' (I can't explain this - if you can you should believe this answer much more).
'hand' becomes 'R' (abbreviation for right, as in the right-hand side).
't' going inside 'doco' is 'docto'.
'docto'+'r'='DOCTOR'
'be enough? bankers to count' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for doctor that I've seen before include "bones" , "Physician" , "Health expert" , "Spike?" , "One treats the ill" .)
