Unusual thrones with six legs (7)
I believe the answer is:
hornets
'six legs' is the definition.
Although both the answer and definition are plural nouns, I can't understand how one could define the other.
'unusual thrones' is the wordplay.
'unusual' indicates an anagram.
'thrones' anagrammed gives 'HORNETS'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for hornets that I've seen before include "Large stinging wasps" , "Large type of wasps" .)
