Dies down in a Psycho hotel (6)
I believe the answer is:
abates
'dies down' is the definition.
(I've seen this before)
'a psycho hotel' is the wordplay.
I cannot really see how this works, but
'a' is found in the answer.
The remaining letters 'bates' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for abates that I've seen before include "Calms down a" , "moderates" , "Goes down like storm" , "Diminishes" , "Grows less intense" .)
