Nap, doze (6)
I believe the answer is:
snooze
I believe this is a double definition.
'nap' is the first definition.
(I know that nap can be written as snooze)
'doze' is the second definition.
(I know that doze can be written as snooze)
(Other definitions for snooze that I've seen before include "Quick nap" , "Catnap" , "Some sleeping" , "A brief nap" , "Sleep lightly" .)
