"Эта школа уже очень старая."

Translation: This school is already very old.

[mosfet07]

FYI: the adjective старый|ая|ое (old) has the cognate nouns старик (an old man) and старуха (an old woman)

[R_Andersson]

Спасибо за информацию! It also has the cognate nouns старец (a old monk (monastic elder)) and старица (an old nun).

"That school is already very old" is not correct?

[Jan.Lodewijk]

Это can be either this or that, isn't it?
