Seeing need for change, they grant wishes (6)
I believe the answer is:
genies
'grant wishes' is the definition.
Although both the answer and definition are plural nouns, I cannot understand how one could define the other.
'seeing need for change they' is the wordplay.
'seeing' can be anagrammed to 'GENIES'.
But, I am not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for genies that I've seen before include "Arabian spirits that live in bottles" , "Islamic spirits" .)
