Abroad, yes, an ancient god (5)
I believe the answer is:
japan
'ancient god' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'abroad yes an' is the wordplay.
'abroad yes' becomes 'jap' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'jap'+'an'='JAPAN'
Can you help me to learn more?
(Other definitions for japan that I've seen before include "black gloss" , "Twelve [VARNISH]" , "It's a string of more than 3,000 islands" , "Glossy coating" , "East Asian island nation" .)
