سلام د ر مورد گرامر سوال داشتم

Question

جمله where to invade next 

گرامرش چیه ؟

منظورم اینه که چرا  where با مصدر to به کار رفته ؟

Answer 1

1- اینجا noun clause بوده که reduced شده -- گشتار کاهش جمله واره ها رخ داده.

I don't know where I should invade next.

Reduced noun clause: I don't know where to invade next.

2- مثلا adjective clause میتونه گشتار کاهش روش رخ بده:

The book which is on the table is mine.

Reduced adjective clause: The book on the table is mine.

3- یا adverbial clause حتی:

I saw a weird scene While I was driving.

Reduced adverbial clause: I saw a weird scene while driving.

4- به ندرت هم content clause های که درباره کل یه جمله هستن:

He eats with his mouth open, which is a ridiculous habit.

Reduced: He eats with his mouth open, a ridiculous habit.
