Or each backward shaver makes a flying machine (9)
I believe the answer is:
aeroplane
'a flying machine' is the definition.
(I've seen this before)
'or each backward shaver' is the wordplay.
'each' becomes 'ea' (abbreviation).
'backward' shows that the letters should be reversed in order.
'shaver' becomes 'plane' (I've seen this in another clue).
'or'+'ea'='orea'
'orea' backwards is 'aero'.
'aero'+'plane'='AEROPLANE'
'makes' acts as a link.
(Other definitions for aeroplane that I've seen before include "What taxis" , "Fixed-wing aircraft" , "Flying craft" , "Flying vehicle" , "Flier" .)
