... recent naturist ends hidden (6)
I believe the answer is:
latent
'hidden' is the definition.
(thesaurus)
'recent naturist ends' is the wordplay.
'recent' becomes 'late' ('late' can be similar in meaning to 'recent').
'ends' says to hollow out the word (remove centre letters).
'naturist' with its centre taken out is 'nt'.
'late'+'nt'='LATENT'
(Other definitions for latent that I've seen before include "Potential, dormant" , "waiting to be discovered" , "Indiscernible" , "Existing but not yet active or visible" , "Existing but not yet developed, say ability" .)
