Hidden talent, maybe (6)
I believe the answer is:
latent
'hidden' is the definition.
(I've seen this before)
'talent maybe' is the wordplay.
'maybe' is an anagram indicator.
'talent' is an anagram of 'LATENT'.
(Other definitions for latent that I've seen before include "Existing but not yet active, say talent" , "Potential not realised" , "Existing but not yet manifest" , "Talent (anag)" , "Not presently active" .)
