More than capable (5)
I believe the answer is:
adept
'more than capable' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for adept that I've seen before include "Thoroughly proficient" , "One who is very skilful" , "Practised" , "who gets the lapis philosophicus secret" , "Dexterous" .)
