Pointless reason for world revolution (4)
I believe the answer is:
love
This clue could be a double definition.
'pointless reason' is the first definition.
The definition and answer can be both related to thinking as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'world revolution' is the second definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'for' acts as a link.
Can you help me to learn more?
(Other definitions for love that I've seen before include "Deep affection" , "See 10" , "1970 film, starring Ali MacGraw and Ryan O'Neal" , "Serenade" , "Nothing for the Williams sisters?" .)
