The Difference between 'One' and 'Ones'
'One' and 'ones' are impersonal pronouns in English. They're used in place of previously mentioned nouns to avoid repetition.
One and Ones
As a personal pronoun (both subject and object), 'one' can be used to refer to 'people in general'.
'One' and 'ones' are both impersonal pronouns. An impersonal pronoun is one that does not refer to a specific person or thing. These pronouns are usually used to refer to an unspecified person or people in general.
- 'One' replaces a singular noun.
- 'Ones' replaces a plural noun.
We often use 'one' or 'ones' in more formal styles of writing. Too much use of it might result in a very formal language (that almost sound unnatural).
The pronoun 'one' replaces singular or one person, animal, or thing.
Here, the noun 'bus' is replaced by 'one'. The adjective 'next' can't be used alone and the repetition of 'bus' doesn't sound natural. Therefore, we replaced 'one' to avoid repetition.
As you can see, we cannot omit the pronoun 'one' and say 'Molly is the tall and Emily is the short'.
'Ones' replaces the nouns that are used in the plural form. They can refer to people, animals or things.
Here, 'ones' replaces 'pants' (a plural noun)
We use 'one' and 'ones':
- after an adjective
- after the definite article 'the'
- after 'which' as a question word
- After demonstrative pronouns
