In Russian, can Это change?

Question

I see other words such as Эти. But i was told Это doesn't change. And does anything else other than adjectives and nouns use the case system?
Thanks

Answer 1

It depends.
Это can be an adjective, in this case it changes and has a lot of forms (for the three genders, two numbers and 6 cases).
When это is a demonstrative pronoun it changes also but in another way.

Эти means "these" in the nominative and accusative cases

Case system exists for pronouns, nouns and adjectives


!!! The next answerer says the pronoun doesn't change but he's wrong.
When you say "I don't know this" in Russian it is "Я этого не знаю" or "What do you mean by this?" is "Что ты этим хочешь сказать?"
It doesn't have gender or number here but it changes according to the case.

Answer 2

It doesn't change in the sense of it being a PRONOUN. You use it as in "THIS is a house". In this case, it doesn't matter if the noun is maculine, feminine or neuter.

But if you want to use it as a demonstrative adjective, then it suffers changes according to gender, number and case.
This second form, see it as "THIS house is big".

Answer 3

It changes all the time...
Kto tebe pro eto skasal?=Who told you about that?
Ya etogo ne znaiu= I do not know about it.
Eta shliapa tebe ne idiot=This hat does not siut you.
Ty prishiol tolko za etim=You came fust for this only?
Eti rebiata plohie=these boys are bad...
etc, etc, etc...

Answer 4
