Architectural feature starting to go green? (8)
I believe the answer is:
moulding
'architectural feature starting' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'go green?' is the wordplay.
I cannot quite see how this works, but
'go' could be 'din' (dinning is a kind of going) and 'din' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for moulding that I've seen before include "Decorative architectural feature" , "going off?" , "Gum on lid (anag)" , "Fillet" .)
