German Present Perfect - Separable Prefix Verbs
German separable prefix verbs can be compared to English verbs like "call up," "clear out" or "fill in." In German the separable prefix is almost always at the end of a sentence.
Separable prefix verbs can be regular, irregular or mixed. Separable prefixes include: ab, an, auf, aus, bei, da, durch, ein, fern, fest, fort, her, hin, los, mit, nach, um, vor, weg, weiter, wieder, zu, and zusammen.
As can be seen, when forming the present perfect of separable prefix (trennbare) verbs, the prefix comes before the “ge,” which is followed by the stem and then ending. Keep in mind that there are regular, irregular and mixed verbs with separable prefixes.
durchführen (to execute, operate, conduct [regular]) = hat durchgeführt
mitbringen (to bring along with [mixed]) = hat mitgebracht
ankommen (to arrive [irregular]) = ist angekommen
