Demonstrative pronouns share the category of number and besides differentiatebetween relative immediacy and relative remoteness of object they point out to: near (this, these) remote (that, those)
The use of this/that, these/those doesn't exclusively depend on the objectively perceived distance. By bringing an object of reference closer to himself a speaker may express some emotional, expressive, evaluative connotations and attitudes: I like these apples better than those bought last week. They approved of this idea of mine and rejected that other one, I spoke to you about recently. I turned around and saw at some distance this lovely-girl. Here comes that awful Jack and all those children of his.
There are universal pronouns including each, every, all and every-compounds: everyone, every body. The last two possess the Case category: Nominative everyone, everybody everything; Genitive everyone 's everybody's.
