Heard two lost from housing for those to be knocked off (5,3)
I believe the answer is:
death row
'housing for those to be knocked off' is the definition.
I can't judge whether this defines the answer.
'heard two lost' is the wordplay.
'lost' indicates an anagram.
'heard'+'two'='heardtwo'
'heardtwo' anagrammed gives 'DEATH ROW'.
'from' is the link.
Can you help me to learn more?
(Other definitions for death row that I've seen before include "location of worst offenders" , "In USA, part of prison where condemned criminals are held" , "Where condemned prisoners are held" , "special facility for condemned prisoners" , "Part of US prison for condemned murderers" .)
