Propositional/clausal information modifying a noun may be introduced in a subordinate clause or it may be expressed through parataxis (sentences juxtaposed), e.g. My friends bought the house that I told you about OR My friends bought the house. I told you about (it/the house/Ø).
Postposed position is the norm/default if a relative clause is used at all. One can also construct sentences like this Example 12, which are similar to correlative relatives, but they are discursively highly marked. They suggest a discourse focus reading, e.g. the head of the relative is a topic or is being emphasized for some reason.
