Makes a bed up in here to spoil one? (6)
I believe the answer is:
debase
'spoil one?' is the definition.
'debase' can be an answer for 'spoil' (thesaurus). I'm not certain of the 'one?' bit.
'makes a bed up in here' is the wordplay.
'DEBASE' is hidden backwards within the letters.
But, I'm unsure how this is indicated.
'to' is the link.
Can you help me to learn more?
(Other definitions for debase that I've seen before include "Lower in quality, reduce the value of" , "Degrade or devalue" , "Lower the character of" , "Lower in value or quality, sometimes currency" , "Humble" .)
