Harry hesitates to ban the rest (6)
I believe the answer is:
siesta
'the rest' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for siesta that I've seen before include "Catnap" , "After lunch nap" , "Afternoon nap in a warm climate" , "Spanish afternoon activity" , "Daytime nap" .)
