Rue lies about vacation? (7)
I believe the answer is:
leisure
'vacation?' is the definition.
(vacation is a kind of leisure)
'rue lies about' is the wordplay.
'about' indicates an anagram.
'rue'+'lies'='ruelies'
'ruelies' anagrammed gives 'LEISURE'.
(Other definitions for leisure that I've seen before include "casual wear" , "Time to rest and enjoy" , "Time for relaxing" , "Freedom from work" , "may suggest fun and games" .)
