In addition to that lost ultimate revolutionary - a real pain in the face perhaps (9)
I believe the answer is:
toothache
'in addition to that lost ultimate revolutionary a real pain in the face perhaps' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'in addition to that lost ultimate revolutionary a' is the wordplay.
I cannot really see how this works, but
'to' is found in the answer.
'revolutionary' could be 'che' (Che Guevara the Marxist revolutionary) and 'che' is present in the answer.
'a' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for toothache that I've seen before include "Dental pain" , "Trouble with choppers" , "Dental problem" , "Cause of sore mouth" , "Odontalgia" .)
