Giants in the gorse possibly (5)
I believe the answer is:
ogres
'giants' is the definition.
(ogre is a kind of giant)
'gorse possibly' is the wordplay.
'possibly' indicates an anagram.
'gorse' is an anagram of 'OGRES'.
'in the' is the link.
(Other definitions for ogres that I've seen before include "Monstrous giants and man-eaters" , "Monsters can be goers" , "Fairytale giants" , "intimidating people" , "Man-eating giants of folklore" .)
