The right woman left the party (5)
I believe the answer is:
revel
'party' is the definition.
(I've seen this before)
'the right woman left' is the wordplay.
I cannot really see how this works, but
'right' could be 'r' (common abbreviation) and 'r' is found within the answer.
'woman' could be 'eve' (Eve is an example) and 'eve' is found in the answer.
'left' could be 'l' (common abbreviation) and 'l' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'the' is the link.
Can you help me to learn more?
(Other definitions for revel that I've seen before include "Take great pleasure" , "Feast riotously" , "Riotous feast" , "Spree" , "Make merry; luxuriate (in)" .)
