I've always used the words much like you - an originator advertises while
everyone else propagates. For instance, R1 might advertise (or originate
would be another good word) an LSA while R2 propagates the LSA by flooding
it. In the interest of accuracy though I've included the exact definitions.
As you can see, the words are defined similarly.

Subject: RE: Advertise or Propagate
But what if we asked a question like below?
- Backbone send several route to Router1.
Configure Router1 to not advertise these route(or some) to any router in
your
netwrok.
Can Router1 have the routes or not?
In other words, should I filter at incoming interface or outgoing
interface?
also silly question?
