noun adjective grammar


学校の窓ガラスを割った生徒に反省文を書かせました。 in this phrase why did we use two を particles, does
it mean two objects are here ?? can anyone explan the sentence structure..any
similar examples also




> 学校の窓ガラスを割った生徒に反省文を書かせました

The key grammar point you are looking for is "relative clause".

The main sentence here is:

> 生徒に反省文を書かせました  
>  _He/she/the teacher_ made the student write an apology

We can describe what kind of student it was with a relative clause (the part
in bold):

> **学校の窓ガラスを割った** 生徒  
>  The student who broke the school's window

The whole relative clause acts like an adjective to describe the noun (生徒)
that comes after it.

I won't go into any further detail because now you know the name of it you
should be able to find entire lessons on the subject.
