Adept, proficient (7)
I believe the answer is:
skilful
I believe this is a double definition.
'adept' is the first definition.
(I know that adept can be written as skilful)
'proficient' is the second definition.
(I know that proficient can be written as skilful)
(Other definitions for skilful that I've seen before include "Adroit" , "Adept, expert" , "Capable" , "exhibiting crafts" , "Very adept and proficient" .)
