High rent Hall curtailed for entrance (7)
I believe the answer is:
enthral
'for entrance' is the definition.
(I've seen this before)
'high rent hall curtailed' is the wordplay.
'high' is an anagram indicator (can mean drunk or on drugs and hence disordered).
'curtailed' means to remove the last letter.
'rent'+'hall'='renthall'
'renthall' with its last letter removed is 'renthal'.
'renthal' with letters rearranged gives 'ENTHRAL'.
(Other definitions for enthral that I've seen before include "Totally fascinate" , "Hold spellbound" , "yoke" , "Beguile" , "Entrance" .)
