Quantifiers: all, every, each, both, neither, either

Meaning and use: all, every each

Quantifiers are words that give us information about the number or amount of something. All, every and each mean the whole number of something in a group, but there are differences in how we use them. In this unit we look at how to use them with nouns.

All or All the is followed by a plural or uncountable noun. Every and each are followed by a singular noun.

  • All (the) students have their own rooms.
  • All (the) information is on the website.
  • Every/Each student has their own room. (OR has his/her own room.)

Every and each can often be used in the same place, but we prefer every when we are thinking about the whole number in a group, and each when we are thinking about the members of the group as individuals.

  • I love every painting by that artist.
  • Each painting is unique.

For emphasising every single one, we must use everynot each.

  • You’ve eaten every chocolate in the box!

For only two things, we can use each but not every.

  • In baseball, how many players are there in each team?

Alland each but not every can be followed by of and a plural noun or pronoun. Notice that each of with a plural noun or pronoun is followed by a singular verb.

  • All of the students have their own rooms.
  • Each of them has their own room.

Meaning and use of both, neither, either

Either is used mainly in questions and negative sentences. Here are some examples of how to use them with nouns:
