Reduce high rent with a cut (8)
I believe the answer is:
truncate
'reduce' is the definition.
(thesaurus)
'high rent with a cut' is the wordplay.
'high' indicates an anagram (can mean drunk or on drugs and hence disordered).
'with' says to put letters next to each other.
'a'+'cut'='acut'
'rent' after 'acut' is 'acutrent'.
'acutrent' anagrammed gives 'TRUNCATE'.
(Other definitions for truncate that I've seen before include "Dock" , "Make shorter by cutting off" , "Lop" , "Cut short" , "Shorten by cutting off the top" .)
