Questions & Answers about Да, этот ресторан хороший.
Why do we use этот instead of это or эта?
Этот is the masculine form of the word "this". We use it here because it directly describes ресторан (restaurant), which is a masculine noun since it ends in a consonant. If the noun were feminine, we would use эта.
Wait, isn't это the word for "this is"? Why can't I say Это ресторан хороший?
Это acts as a generic "this is" when you are introducing something, like Это ресторан (This is a restaurant). But when you want to say "this specific object", the word for "this" must match the noun's gender. That is why we use the masculine Этот ресторан (This restaurant) to be the subject of our sentence.
Where is the word for "is" in this sentence?
In Russian, the present tense of the verb "to be" (am, is, are) is almost always skipped. To say "this restaurant is good", you literally just say "this restaurant good" (этот ресторан хороший).
Why does the adjective хороший (good) end in -ий instead of the usual masculine ending -ый?
