Fabulous equestrian with six limbs! (7)
I believe the answer is:
centaur
This could be a double definition.
'fabulous equestrian' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'with six limbs' is the second definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
Can you help me to learn more?
(Other definitions for centaur that I've seen before include "Mythological horse-man" , "Fabulous horse-man" , "Mythological creature" , "Mythical hybrid" , "Mythic man-horse" .)
