Revolutionary provided with Guevara's microfilm (5)
I believe the answer is:
fiche
'microfilm' is the definition.
Both the answer and definition are singular nouns.
Perhaps they are linked in a way I don't understand?
'revolutionary provided with guevara's' is the wordplay.
'revolutionary' says the letters should be written in reverse (letters revolve around).
'provided' becomes 'if' (eg 'provided it's sunny' means 'if it's sunny').
'with' means one lot of letters go next to another.
'guevara' becomes 'che' (revolutionary Che Guevara).
'if' backwards is 'fi'.
'fi'+'che'='FICHE'
Can you help me to learn more?
(Other definitions for fiche that I've seen before include "Small film" , "Archived record" , "bit of film" , "data store" , "Card bearing data" .)
