Remove — kill (7)
This clue is a double definition.
'remove' is the first definition.
(I know that remove can be written as take out)
'kill' is the second definition.
(I know that kill is a more specific form of the action take out)
(Other definitions for take out that I've seen before include "kebab, perhaps" , "As gangster, kill" , "Extract; kill" , "Remove from within" , "Remove; escort" .)
