A giant among stars (5)
I believe the answer is:
orion
This clue might be a double definition.
'a giant' is the first definition.
(thesaurus)
'stars' is the second definition.
(Orion is a constellation)
'among' acts as a link.
I am not very happy about this link. It may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for orion that I've seen before include "Rigel constellation" , "Prominent constellation" , "Group in heaven" , "Constellation in the form of a belt" , "hero" .)
