Pronouns

A pronoun is a word that can be used in place of a noun or a noun phrase, as the word itself tells us: pro-noun. We do not normally put a noun after a pronoun except in special combinations such as you students she-bear, etc. We use pronouns like he she, it and they when we already know who or what is referred to. This saves us from having to repeat the name or the noun whenever we need to refer to it: John arrived late last night. He had had a tiring journey I wrote to Kay and told her what had happened. However, we normally use I/me, you and we/us for direct reference to ourselves or the person(s) addressed and not in place of nouns.

4.2.2 Determiners [> 3.1] compared with pronouns
Determiners are always followed by a noun. Words such as some [>
5.10] and this [> 4.32] followed by a noun function as determiners.
When they stand on their own, they function as pronouns:

/ want some milk, (some + noun, functioning as determiner)
/ want some (some on its own, functioning as pronoun)

/ want this book (this + noun, functioning as determiner)
/ want this (this on its own, functioning as pronoun)
