Talented, topped chart (4)
I believe the answer is:
able
'talented' is the definition.
(both can mean skilled)
'topped chart' is the wordplay.
'topped' means to remove the first letter (to top something is to remove its top).
'chart' becomes 'table' (a table of information).
'table' with its first letter taken away is 'ABLE'.
(Other definitions for able that I've seen before include "Competent, having ability" , "Capable or proficient" , "Skilled" , "Efficient" , "Fitted" .)
