A pronoun is part of a speech that points to objects, signs and quantities, but does not specifically identify them.
So, there was a white shaggy December. He quickly approached the half (MA Bulgakov).
His personal pronoun refers to the month referred to in the first sentence, which allows the writer to avoid repeating the same word.
There is an hour, in the night, of universal silence (FI Tyutchev).
Pronouns indicate some indefiniteness of the feature of the subject, but does not name this feature. It can be replaced by any adjective (unknown, indefinite).
Suddenly several people jumped out of the forest and began to wave their hands desperately (K. Simonov).
The pronoun indicates a number of objects, but does not specify a specific number. It can be replaced by any number (five, eight, thirteen, twenty).
Pronouns point to objects and have some signs of nouns:
I, you, you, we, he, he, she, she, they, myself, who, what, who, something, something, anyone, anything, anyone, anything, Someone, someone, something, nobody, nothing, there is nobody, there is nothing; Who? what?
Pronouns I, we, you, you, who point to animate objects. Some pronouns have a single and a plural:
He, she, it – they are.
The pronoun he points to the masculine subject, it is feminine. and it is of a...middle kind.
All these words change by case, and they retained traces of pronoun changes in ancient times, that is, there is a change in the root:
I – me, me, me, about me;
You – you, you, you, about you;
We are us, us, us, about us.
Pronouns that indicate the subject’s feature:
My, your, your, your, your, that, this, such, such, such, such, everyone, everyone, any, whole, all, other, itself, most, other, which, which, whose, some, some, someone, someone’s, someone’s, some, some, some, some, no, nobody’s; which one? what? which the? whose?
They have the properties of adjectives: they vary in case, number and gender, for example:
Any book, any work, any person, any news, about any news, with any news.
Unlike qualitative adjectives, they do not have a short form.
Pronouns that indicate the number. very little:
How much, so much, so much, so many, so many, some, some, not at all; how?
They change only by case.

I do not know who this old woman is (the predicate).
I do not want to upset you with anything (addition).
