Gawain or Galahad, say (6)
I believe the answer is:
knight
I believe this is a double definition.
'gawain' is the first definition.
(thesaurus)
'galahad say' is the second definition.
(I know that Galahad has the has the occupation knight)
(Other definitions for knight that I've seen before include "Old freelance" , "Chess piece shaped like hors's head" , "nobleman" , "- - errant" , "cavalier" .)
