Demostrative pronouns
Demostrative pronouns serve basically the same purpose as do the demostrative adjectives.
The main difference is that the pronouns stand for nouns rather than modify them. 
Demostrative pronouns replaces a noun while also pointing to it.
Demostrative pronouns are identical to the demostrative adjectives, except that most use accent marks 
but the accent are used only to distinguish adjectives from pronouns
and  there is a neuter demostrative pronoun form (esto, eso, aquello). They do not have accent marks because
the demostrative adjectives don't have a neuter form.
You can see different charts with these demostrative pronouns.
