Why are these correct?
The work I am doing is easy.
The house he lives at.
The book I am writing is about different realms.
The man I was helping thanked me.
The ant I was blocking the road of.
The school I go to.
Shouldn't "I am doing", "lives at", "writing", "was helping", "blocking", and "go" be at the front? Could you please explain the grammar here? Thank you.
