Gifted leader dismissed from board (4)
I believe the answer is:
able
'gifted' is the definition.
(I've seen this in another clue)
'leader dismissed from board' is the wordplay.
'leader dismissed from' means to remove the first letter.
'board' becomes 'table' (both can mean food).
'table' with its initial letter removed is 'ABLE'.
(Other definitions for able that I've seen before include "Having considerable skill" , "Having the power, skill or means (to do something)" , "Proficient; skilful" , "See 10" , "Having the ability to do something" .)
