Midday snooze (6)
I believe the answer is:
siesta
'midday snooze' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for siesta that I've seen before include "Afternoon relaxation" , "Seat is found for a Spanish rest period" , "Daytime nap" , "After lunch nap" , "PM snoozing?" .)
