Artist working in opera house abroad (5)
I believe the answer is:
monet
'artist' is the definition.
(painter Claude Monet)
'working in opera house abroad' is the wordplay.
I cannot really see how this works, but
'working' could be 'on' (on can mean working or activated) and 'on' is located in the answer.
'opera house' could be 'met' (short for the Metropolitan Opera House in New York) and 'met' is located in the leftover letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for monet that I've seen before include "Giverny painter" , "Met no impressionist painter" , "French artist shown in ..." , "Claude --, French impressionist painter" , "he painted Rouen Cathedral" .)
