European Monetary Union gets the bird (3)
I believe the answer is:
emu
'the bird' is the definition.
(emu is a type of bird)
'european monetary union' is the wordplay.
'european' becomes 'e' (abbreviation e.g. EU).
'monetary union' becomes 'mu' (this might be a standard abbreviation I've not previously seen).
'e'+'mu'='EMU'
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for emu that I've seen before include "Native Australian bird" , "Australian non-flyer" , "Large Australian flightless bird" , "Flightless Aus. bird" , "Aussie runner" .)
