Fish lying on the bed? (6)
I believe the answer is:
kipper
'fish' is the definition.
(type of fish)
'lying on the bed?' is the wordplay.
'lying' becomes 'per' (I can't explain this - if you can you should believe this answer much more).
'on' says to put letters next to each other.
'the bed?' becomes 'kip' (I've seen this in another clue).
'per' put after 'kip' is 'KIPPER'.
Can you help me to learn more?
(Other definitions for kipper that I've seen before include "Narcoleptic" , "One yet to wake" , "Cured or smoked herring" , "One not awake" , "Cured fish (one having forty winks?)" .)
