Player at rest, I gathered (7)
I believe the answer is:
artiste
'player' is the definition.
(thesaurus)
'at rest i gathered' is the wordplay.
'gathered' indicates an anagram.
'at'+'rest'+'i'='atresti'
'atresti' anagrammed gives 'ARTISTE'.
(Other definitions for artiste that I've seen before include "One entertaining" , "nightclub entertainer?" , "Attires like entertainer" , "Theatre performer" , "A sitter for a performer" .)
