A doctor with occupational therapy, one bound to be skilful (6)
I believe the answer is:
adroit
'be skilful' is the definition.
(thesaurus)
'a doctor with occupational therapy one bound' is the wordplay.
'doctor' becomes 'dr' ('Dr' can be a synonym of 'doctor'**).
'with' is a charade indicator (letters next to each other).
'occupational therapy' becomes 'ot'.
'one' becomes 'i' (Roman numeral).
'bound' means one lot of letters goes inside another.
'ot' placed around 'i' is 'oit'.
'a'+'dr'+'oit'='ADROIT'
'to' is the link.
(Other definitions for adroit that I've seen before include "Quick or adept" , "Apt" , "Skilful, dexterous" , "handy" , "Quick and clever in action or thought" .)
