Top of sofa bed to fit man (6)
I believe the answer is:
slayer
'fit man' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'top of sofa bed' is the wordplay.
'top of' indicates taking the first letters.
'bed' becomes 'layer' (I've seen this in another clue).
The initial letter of 'sofa' is 's'.
's'+'layer'='SLAYER'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for slayer that I've seen before include "Violent killer" , "Violent murderer" , "Butcher" , "Relays to killer" , "Relays (anag)" .)
