Soldier and me back to share international movement (10)
I believe the answer is:
emigration
'international movement' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'soldier and me back to share' is the wordplay.
'soldier' becomes 'GI' (GI can mean a US soldier).
'and' means one lot of letters go next to another.
'back' shows that the letters should be reversed in order.
'to share' becomes 'ration' (ration is a kind of share).
'gi'+'me'='gime'
'gime' backwards is 'emig'.
'emig'+'ration'='EMIGRATION'
Can you help me to learn more?
(Other definitions for emigration that I've seen before include "Imagine rot (anag.)" , "Departure from country" , "Act of leaving one's own country for good" .)
