Terribly ill on beer: is it revolting? (9)
I believe the answer is:
rebellion
'revolting?' is the definition.
(I've seen this before)
'terribly ill on beer' is the wordplay.
'terribly' is an anagram indicator.
'ill'+'on'+'beer'='illonbeer'
'illonbeer' with letters rearranged gives 'REBELLION'.
'is it' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for rebellion that I've seen before include "Coup d'tat" , "Uprising" , "Insurgency" , "Revolting" , "insurgence" .)
