Revolutionary back again, starts shouting words of appreciation (6)
I believe the answer is:
cheers
'words of appreciation' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Maybe you can see an association between them that I can't see?
'revolutionary back again starts shouting' is the wordplay.
'revolutionary' becomes 'che' (Che Guevara the Marxist revolutionary).
'back' shows that the letters should be reversed in order.
'again' becomes 're' (prefix meaning 'again').
'starts' says to take the initial letters.
The initial letter of 'shouting' is 's'.
're' written backwards gives 'er'.
'che'+'er'+'s'='CHEERS'
Can you help me to learn more?
(Other definitions for cheers that I've seen before include "Ta - ta-ta" , "Shouts of applause, or drinking toast" , "Encouragement" , "Accolade" , "Ta; gives comfort to" .)
