Just for fun, a woman stands between the two sides (5)
I believe the answer is:
revel
'just for fun' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's an association between them I don't understand?
'a woman stands between the two sides' is the wordplay.
I cannot quite understand how this works, but
'woman' could be 'eve' (Eve is an example) and 'eve' is found in the answer.
'sides' could be 'rl' (abbreviations for left and right) and 'rl' is present in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for revel that I've seen before include "Feast riotously" , "Rejoice" , "Merrymaking" , "Paint the town red" , "Be festive, enjoy" .)
