Article on huge amount of fumes in Dublin, maybe (3,3,5)
I believe the answer is:
the big smoke
'dublin maybe' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'article on huge amount of fumes in' is the wordplay.
'article' becomes 'the' (the definite article in English).
'on' means one lot of letters go next to another.
'huge' becomes 'big' (similar in meaning).
'amount of fumes in' becomes 'smoke' (I can't justify this - if you can you should give a lot more credence to this answer).
'the'+'big'+'smoke'='THE BIG SMOKE'
Can you help me to learn more?
(Other definitions for the big smoke that I've seen before include "Perfecto, perhaps" , "Name given to London" .)
