Q:

Use of “heraus” in the phrase “aus der Situation heraus”

I'm confused by the use of word heraus in the following sentence:

Dann entscheiden Sie aus der Situation heraus, wen Sie wem zuerst vorstellen.

What is the role of this word here? I noticed that dict.cc entry for English out of gives its translation as aus … (heraus). Does it mean that heraus is optional here and can be dropped from the sentence? Or would it be wrong for some reason?

A:

It's a particle. The sentence has the same meaning without heraus, because aus already means out of.
Those particles can be confusing first but as soon you know the pairs (aus/heraus, in/hinein, durch/hindurch, über/hinüber, auf/hinauf, unter/drunter etc.) they can be quite helpful when listening to German. The crucial information is doubled.
People giving you directions are often going to use them to help you remember the way.
You don't have to use particles in your own speech but doing so will immediately make you sound more German. Just don't overdo it.
