Revised FA rules getting thumbs-down (7)
I believe the answer is:
refusal
'thumbs-down' is the definition.
I can't tell whether this definition defines the answer.
'revised fa rules getting' is the wordplay.
'revised' is an anagram indicator.
'getting' is a charade indicator (letters next to each other).
'fa'+'rules'='farules'
'farules' anagrammed gives 'REFUSAL'.
Can you help me to learn more?
(Other definitions for refusal that I've seen before include "Chance to decline" , "Dissent" , "Act of declining to take or accept something" , "The turning down of a request" , "Instance of a horse not jumping" .)
