Saw marine’s chopper lifting - who, me? (5)
I believe the answer is:
axiom
'saw marine's chopper lifting who me?' is the definition.
'axiom' can be an answer for 'saw' (saw can mean a saying or idea). I'm not sure about the rest of the definition.
'chopper lifting who me?' is the wordplay.
'chopper' becomes 'ax'.
'lifting' is a reversal indicator.
'who me?' becomes 'moi' (I've seen this in another clue).
'moi' back-to-front is 'iom'.
'ax'+'iom'='AXIOM'
Can you help me to learn more?
(Other definitions for axiom that I've seen before include "Statement regarded as self-evidently true" , "Obviously true statement" , "Truth assumed to be self-evident" , "saw" , "It's taken for granted" .)
