A time to rest or go out for the night? (6)
I believe the answer is:
asleep
'a time to rest' is the definition.
I can't judge whether this definition defines the answer.
'go out for the night?' is the wordplay.
'go out' becomes 'sleep'.
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'the night?' becomes 'a' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'sleep' after 'a' is 'ASLEEP'.
'or' is the link.
Can you help me to learn more?
(Other definitions for asleep that I've seen before include "Like kippers" , "Knitting up the ravelled sleeve of care" , "Dead to the world" , "Please be at rest, oddly" , "Having forty winks" .)
