auszustoßen

Ausstoßen is a German verb meaning to emit, discharge or eject something, and also to expel someone from a place or position. The prefix aus- signals outward motion, combined with stoßen to push or strike. In standard usage the infinitive is ausstoßen; the form auszustoßen is not common in modern orthography and is generally considered nonstandard, though it may appear in some inflected constructions or as a misspelling in informal writing.

The verb has several core senses. One is to emit or discharge substances or energy, such as gases, vapors, or liquids: for example, a car engine stößt Abgase aus (emits exhaust gases). Another sense is to exhale or to push air out: jemand stößt Luft aus. A third sense is to oust or eject someone from a group, office, or position: eine Person aus dem Amt ausstoßen means to remove or expel them from office or membership.

Grammatical notes: ausstoßen is a separable-prefix verb. In the present tense the prefix may separate: ich stöße Luft aus, du stößt Luft aus, er stößt Luft aus. In perfect tense you use ausgestoßen with haben: er hat Luft ausgestoßen. The passive can be formed with werden: Luft wird ausgestoßen. The verb also appears in the sense of expulsion from a group: jemand wird aus dem Verein ausgestoßen.

Related terms include ausströmen (to flow out, particularly liquids or gases in a continuous stream) and abgasen (to emit exhaust gases). In technical contexts, ausstoßen often translates to emit or discharge, while in political or social contexts it can mean to oust or expel.
