Is this sentence correct

Hi,
I really don't understand clearly what you mean here. Perhaps this.

We cannot impede a decision made by our country, not now, nor anytime!

Best wishes, Clive

But can we say: "We cannot impede decision made by our country, not now, nor anytime!"?

*decision as in all decision or more general than decisions

I don't understand what you mean by that. A decision is countable.

I initially meant: "We cannot impede on decision made outside of our country, not now, nor anytime!

But I guess "impede on" does not even exist.

wholegrainBut I guess "impede on" does not even exist.

In the version of English that I speak, you do not "impede on" something, you just "impede" it.

However, Google shows that some people (apparently including proficient native speakers) do say "impede on", so it may be acceptable to some. There may also be regional differences I suppose. Havi

But why do I hear sentences like:

"Man is a beast"

"Well-being in developed nation"?

wholegrain"Man is a beast"

"Man" here is an abstraction of "a man" that behaves as an uncountable noun and therefore does not need an article. You will occasionally come across unusual cases like this, but don't let them distract you from the rules that apply 99% of the time.

wholegrain"Well-being in developed nation"?

Nouns when used as names for the entire class of such things, can be written without an article at will?

Then can developed nation be written without an article if it refer to all of them?

wholegrainNouns when used as names for the entire class of such things, can be written without an article at will?

Not at will, no. You can only do this with uncountable nouns. "Nation" is always a countable noun, so you cannot write, for example, "Developed nation is ..." to refer to the entire class of developed nations. You would instead say "Developed natio

I don't know why you think it refers to both a specific instance and a general instance, but if I understand well you are saying that Man can be general because we are about 6 billion and it's not something a person can count; whereas, there is only about 200 countries and we can count them all, so nation must be always in plural and can never refer to a general class when speaking of them all?
