Lifting device held by reportedly high queen for person who forcibly takes over vehicle (8)
I believe the answer is:
hijacker
'person who forcibly takes over vehicle' is the definition.
'hijacker' can be an answer for 'person' (hijacker is a kind of person). I'm unsure of the remainder of the definition.
'lifting device held by reportedly high queen' is the wordplay.
'lifting device' becomes 'jack' (I've seen this before).
'held by' means one lot of letters goes inside another.
'reportedly high queen' becomes 'hier' (I can't explain this - if you can you should believe this answer much more).
'jack' placed into 'hier' is 'HIJACKER'.
'for' is the link.
Can you help me to learn more?
(Other definitions for hijacker that I've seen before include "One seizing control of plane" , "One who takes control of plane by force" , "One forces a pilot to fly to a chosen destination" , "one will divert passengers unexpectedly" , "Seizer of vehicle controls" .)
