Verbs with Separable Prefixes

Some verbs have a prefix that moves around in the sentence, depending on what form the verb takes. In the infinitive form, the prefix is attached, like "ausgehen" (to go out). If the verb is conjugated (in present or simple past tense), the prefix appears at the end of the clause, as in "Ich gehe heute Abend aus." For more information about these verbs, see the examples for individual verbs or read these explanations from Grimm Grammar: present tense, conversational past tense (Perfekt).
