I. TheoryIn German, certain prefixes are added to verbs to add nuance to the original verb’s meaning or produce an entirely different meaning. These prefixes are typically prepositions and when the verb is conjugated, they separate from the verb stem and take a position later in the sentence.
Similar verbs are seen in English. They are called phrasal verbs:
To break up: The police broke the fight up.
To turn off: Before leaving, I turn the lights off.
To hand out: I handed the posters out.
zustimmenIch stimme dir zu.
I agree with you.
einladenIch lade sie zur Party ein.
I invite her to the party.
ankommenWann kommt der Zug an?
When does the train arrive?
