Cant get up before a quiet sleep (6)
I believe the answer is:
catnap
'sleep' is the definition.
(I know this)
'cant get up before a quiet' is the wordplay.
'cant' becomes 'cat' (I can't justify this - if you can you should give a lot more credence to this answer).
'get up' says the letters should be written backwards.
'before' is a charade indicator (letters next to each other).
'a' becomes 'an'.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'an' put after 'p' is 'pan'.
'pan' written backwards gives 'nap'.
'cat'+'nap'='CATNAP'
Can you help me to learn more?
(Other definitions for catnap that I've seen before include "go out briefly" , "Kip" , "Short sleep" , "little snooze" , "Drop off" .)
