Judge rarebit harshly (7)
I believe the answer is:
arbiter
'judge' is the definition.
(I know that arbiter is a type of judge)
'rarebit harshly' is the wordplay.
'rarebit' anagrams to 'ARBITER'.
But, I am not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for arbiter that I've seen before include "Judge to decide a disputed issue" , "Referee or judge of rarebit" , "Someone with the power to settle the matter" , "One decides in disputes" , "Judge, umpire" .)
