Second fellow has quiet nap (5)
I believe the answer is:
sleep
'nap' is the definition.
(I know that nap is a more specific form of the action sleep)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for sleep that I've seen before include "crash" , "Drop off" , "Shut-eye" , "Slumber" , "''... that knits up the ravell'd sleeve of care'' (Macbeth)" .)
