Sleep for a bit with secretary in leather (5)
I believe the answer is:
nappa
'secretary in leather' is the definition.
'nappa' can be an answer for 'leather' (I've seen this before). I'm unsure of the 'secretary in' bit.
'sleep for a bit with' is the wordplay.
'sleep' becomes 'nap' (a nap is a short sleep).
'for' says to put letters next to each other.
'a bit with' becomes 'pa' (I can't explain this - if you can you should give a lot more credence to this answer).
'nap'+'pa'='NAPPA'
Can you help me to learn more?
(Other definitions for nappa that I've seen before include "Sort of kid, perhaps" , "leather" .)
