Hi,
Please look the sentence "This is NO easy task". What part of speech is "NO" in the sentence? My English-Japanese dictionaries say this NO is an Adjective because it modifies and negates the phrase "easy task". But I understand that "task" is a Countable Noun and if I am right, I think we maybe need to put some determiner before "no (Adj) + easy (Adj) + task (countable N)". So I think this "NO" is rather a kind of negative article (or determiner) that is equivalent to the German "KEIN". Am I right?
I can't compare to the German language. However, I would agree that 'no' is a determiner here.
We also say things like
Tom is no honest man.
No excuse(s) will be accepted.
No man is an island.
No bus stops on Main Street.
Best wishes, Clive
