After using every, should it be singular or plural? [closed]

Solution 1:

The singular is correct in your example. "Not every student is as rude, as you mentioned.

Every

from Cambridge English Grammar Today Link

Every is a determiner.

Every meaning ‘each member of a group’

We use every + singular noun to refer individually to all the members of a complete group of something:

There’s a photograph on the wall of every child in the school.

Try to answer every question.

When "every" refers to the subject of the clause, we use a singular verb:

Every player wants to be in a winning team.

Not: Every player want ...

Every cook needs good knives and a chopping board.

The negative of every is normally not every:

BUT not every noun has a plural form.

We use singular pronouns and possessives to refer back to every + noun, especially in more formal styles, and especially when what we refer to is not human:

Every store has a manager in charge of it.

Every area has its own park.

In less formal styles, the pronoun or possessive may be plural:

Every student gets a laptop. They have to give it back at the end of the course.

Every user has his (or her) own password.
