Greeting leather-clad male who might take you out? (6)
I believe the answer is:
hitman
'might take you out?' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'greeting leather-clad male' is the wordplay.
'greeting' becomes 'hi' (hi is a kind of greeting).
'leather' becomes 'tan' (tan can mean to convert into leather).
'clad' means one lot of letters goes inside another (clad can mean covered by).
'male' becomes 'm' (common abbreviation).
'tan' enclosing 'm' is 'tman'.
'hi'+'tman'='HITMAN'
'who' is the link.
Can you help me to learn more?
(Other definitions for hitman that I've seen before include "Assassin" , "Hired gun" , "killer" , "offer?" .)
