Fixed penalty is a lot (7)
I believe the answer is:
aplenty
'a lot' is the definition.
Both the definition and answer are adverbs.
Perhaps they are linked in a way I don't understand?
'fixed penalty' is the wordplay.
'fixed' indicates an anagram.
'penalty' is an anagram of 'APLENTY'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for aplenty that I've seen before include "more than enough" , "heaps" , "by the score" , "lots of it" , "In abundance" .)
