Ingenious; skilful (6)
I believe the answer is:
clever
This clue is a double definition.
'ingenious' is the first definition.
(I know that ingenious can be written as clever)
'skilful' is the second definition.
(I've seen this before)
(Other definitions for clever that I've seen before include "Sharp and able" , "expert" , "Skilful, adroit" , "Adroit, ingenious" , "Quick-minded" .)
