Cover electric vehicle crossing North Pole after overturning (7)
I believe the answer is:
envelop
'cover' is the definition.
(enveloping is a kind of covering)
'electric vehicle crossing north pole after overturning' is the wordplay.
'electric vehicle' becomes 'ev' (this could be a standard abbreviation of which I'm unaware).
'crossing' means one lot of letters goes inside another (to cross can mean to go over or around).
'north' becomes 'N' (abbreviation).
'after overturning' says the letters should be written backwards.
'pole' backwards is 'elop'.
'ev' enclosing 'n' is 'env'.
'env'+'elop'='ENVELOP'
Can you help me to learn more?
(Other definitions for envelop that I've seen before include "Enclose" , "Enfold, enwrap" , "Surround completely" , "Obscure" , "blanket" .)
