Potential victims, punched, keel over (3,4)
I believe the answer is:
hit list
'potential victims punched keel over' is the definition.
I can't tell whether this definition defines the answer.
'punched keel over' is the wordplay.
'punched' becomes 'hit' (hit with fists).
'keel over' becomes 'list' (list can mean to tilt or keel over).
'hit'+'list'='HIT LIST'
Can you help me to learn more?
(Other definitions for hit list that I've seen before include "Names of victims to be" , "Top ten" , "potential victims?" , "it's best not to be on it" , "Names to be rubbed out?" .)
