Type of sentence and putting a comma

[sash2008]

What is the type of the following sentence?
This is the bus by which I go to shcool.
and should I put a comma before (by which)?

[susiedqq]

This is the bus in which I go to school.

(simple sentence)

[supada]

This is the bus in which I go to school.

(simple sentence)

Dear susiedqq,

If breaking this sentence in two, would they be as following?

- This is the bus.
- I go to school in this bus.

Is it correct?

[susiedqq]

This / is / bus

(in which I go to school is an adjective clause describing the bus)


This is the bus that got in an accident (desribes the bus)

This is the bus I take to school. (describes the bus)

[sash2008]

Yes I agree with you
I think the prepostion should be ''by'' bus
and I want to know should I put a comma after bus?

[supada]

This / is / bus

(in which I go to school is an adjective clause describing the bus)


This is the bus that got in an accident (desribes the bus)

This is the bus I take to school. (describes the bus)

I see. At first I thought "in" would be from the second sentence so it was used to connect two sentences. Now I get it.

Thanks.

Dear sash2008,

No, you shouldn't.
