Questions & Answers about این مدرسه بزرگ است.
این means this. In Persian you usually don’t need یک (a/an/one) in simple “This is …” sentences.
- این مدرسه بزرگ است. = This school is big.
You can add یک if you mean this is a (particular) school (emphasizing category), but it often sounds unnecessary in a basic description.
Grammatically این مدرسه is a noun phrase: this school. Then بزرگ است is the predicate: is big.
So the structure is: [subject] + [adjective] + است.
بزرگ is an adjective meaning big/large. In Persian, predicative adjectives (after a noun meaning “is big”) come after the subject:
- مدرسه بزرگ است = The school is big.
(Unlike English, where the adjective comes after is, Persian puts بزرگ before است.)
