Is going back East, perhaps, for a rest (6)
I believe the answer is:
siesta
'a rest' is the definition.
(thesaurus)
'is going back east perhaps' is the wordplay.
'going back' says the letters should be written backwards.
'perhaps' is an anagram indicator.
'is' written backwards gives 'si'.
'east' anagrammed gives 'esta'.
'si'+'esta'='SIESTA'
'for' acts as a link.
(Other definitions for siesta that I've seen before include "Afternoon nap in a warm climate" , "PM snoozing?" , "Diurnal nap in Spain" , "rest of the Spaniards" , "Afternoon rest" .)
