- Americans are puzzled
- Americans puzzled
Which one is correct? I believe 2nd one is grammatically correct, but I see the usage of 1st also.
They are both correct, when used properly. The problem is, they're phrases, not complete sentences (sort of). Consider the following two sentences:
1) Americans are puzzled by the alien spacecraft hovering over Montana.
2) Americans puzzled over the alien spacecraft hovering over Montana.
In the first sentence, Americans (as a whole) are confused and confounded by an alien spacecraft hovering over a state.
In the second sentence, Americans are thinking about an alien spacecraft hovering over a state. They are still confused, but are thinking about it - why is it there, what is it doing, is it stealing our cows, etc.
Both phrases could be used in certain situations. The only one that is a sentence on its own, however, is "Americans are puzzled." This states that Americans in general are attempting to figure something out (what, we don't know).
Both are correct, but distinguished based on usage.
Americans puzzled: It is past tense with active voice. e.g.> Americans puzzled rest of World by their technology.
Americans are puzzled: It is a present tense with passive voice. e.g.> Americans are puzzled by the Russians' technology.
