Eastern European going west? Get away! (5)
I believe the answer is:
elope
'get away' is the definition.
(to elope is to run away to get married)
'eastern european going west?' is the wordplay.
'eastern' becomes 'e'.
'european' becomes 'pole' (Pole is an example).
'going west?' says the letters should be written in reverse.
'e'+'pole'='epole'
'epole' backwards is 'ELOPE'.
(Other definitions for elope that I've seen before include "Run away to Gretna Green?" , "Abscond for amorous purposes" , "Run away with one's beloved" , "Bolt" , "Run away in secret" .)
