European tax return has power, but he lives abroad (5)
I believe the answer is:
expat
'he lives abroad' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'european tax return has power' is the wordplay.
'european' becomes 'E' (abbreviation e.g. EU).
'return' shows that the letters should be reversed in order.
'has' means one lot of letters goes inside another.
'power' becomes 'p' (symbol in physics).
'tax' written backwards gives 'xat'.
'xat' going around 'p' is 'xpat'.
'e'+'xpat'='EXPAT'
'but' acts as a link.
Can you help me to learn more?
(Other definitions for expat that I've seen before include "one settled abroad" , "Person living permanent in a foreign country" , "One living in foreign country" , "Exile, in short" , "he has emigrated" .)
