DEMONSTRATIVE PRONOUNS

Demonstrative pronouns

Demonstrative pronouns have the same form as the demonstrative adjectives, but are used without the nouns to which they refer. In the singular, when designating a specific object, the pronoun "one" is often added:

• These tomatoes are fresher than those.
• These are better than those.
• Would you like a little of this?
• That strikes me as really weird!
• The book is more interesting than that one. 

In front of a relative pronoun, the demonstrative pronoun becomes "the one" or "the ones" (when speaking of things), or "he / she who", "they who" (when speaking of people):

• This film is the one that you hated so much.
• He who eats well works well.
• This pen is the one with which the President signed the new law.
