Skilful, adroit (6)
I believe the answer is:
clever

'skilful' is the first definition.
(I've seen this before)
'adroit' is the second definition.

(Other definitions for clever that I've seen before include "Bright - ingenious" , "Smart or quick at learning" , "Deft, able, bright" , "Bright, quick-witted, intelligent" , "Sharp-witted, intelligent" .)
