Unit 8.2

One and Ones



One and ones are replacing words that are used to avoid repetition.


When we use one and ones we apply the following structures:

  • one: for singular countable nouns;
  • ones: for plural countable nouns.

We do not use them with uncountable nouns.



  • I would like a waffle. Just a small one with some cream and berries.
  • This novel is more important in literature than that one.
  • She is the tallest one of us. 
  • They have a new camera, it’s the dark coloured one I saw in the newspaper.


  • I really like these drawings, the ones which Peter drew.
  • He needs new photos. The ones that I took are too bright.
  • We have several things to discuss, let’s start from the most important ones. 
  • They saw new paintings of Joanna, the ones which are at the exhibition.


We use one and ones to avoid repeating unnecessary words (a singular or plural countable noun).


We use one and ones to avoid repetitions.

  • One is used instead of singular countable nouns.
  • Ones is used instead of plural countable nouns.

For example:
— “There is a phone on the table. The black one is mine.” = Phone is a singular countable noun.
— “There are 3 phones on the table. The black ones are mine.” = Phones is a plural countable noun.

Let’s revise this content within the {Form} section. Take a look at the {Example} section that shows its use within a context.
