Learn English – Can an adjective be used in a plural form

adjectivesamerican-englishbritish-englishgrammaticality

As we know, an adjective modifies a noun and sometimes a noun also modifies a noun and works as an adjective. But my question is, can an adjective or a noun be used in a plural form to modify a noun in English. I have asked this as I read it on a news website.

On the news website:

"These women will also look for younger men. And then you start seeing
men in the streets fighting."

As per my opinion it should have been used:

"These women will also look for younger men. And then you start seeing
men in the street fighting."

Best Answer

In your example, the sentence

These women will also look for younger men. And then you start seeing men in the streets fighting.

could be rephrased as:

These women will also look for younger men. And then you start seeing men fighting in the streets.

The word streets here is not being used as an 'adjectivized noun'. The writer does not want to stress that the men are engaged in 'street-fighting', he wants to say that a passer-by will start noticing fighting men now and then in the streets.

Had the author wanted to say what you thought he wanted, he would have written, for instance:

.. And then you start seeing men engaged in street fights.

A noun, when used in the adjective role, cannot assume the plural form. Some English nouns, however, look as if they are in the plural: news, athletics, although they are not really. Hence, we have a news reporter, an athletics coach - these may mislead a non-native speaker sometimes.
