Demonstrative Pronoun – English editing.

The demonstrative pronouns are:
This, that, these, those.
When these words stand alone, they are pronouns; for example, in sentences like this:
The strong – those in powerful Unions – gained at the expense of the weak.
They can also be used before a noun, in which case they are not pronouns but Determiners:
This decision will cause greater uncertainly.
