Gifted man in marquee with news boss (8)
I believe the answer is:
talented
'gifted' is the definition.
(I know that gifted can be written as talented)
'man in marquee with news boss' is the wordplay.
'man' becomes 'Al' (man's name).
'in' indicates putting letters inside.
'marquee' becomes 'tent' (marquee is a type of tent).
'with' is a charade indicator (letters next to each other).
'news boss' becomes 'ed' (short for editor).
'al' going within 'tent' is 'talent'.
'talent'+'ed'='TALENTED'
(Other definitions for talented that I've seen before include "Having a natural aptitude or skill" , "Able" , "Showing a natural aptitude" , "Having an unusual amount of ability" , "Clever" .)
