trennst

Trennst is the second-person singular present tense form of the German verb trennen. The verb means to separate, detach, or divide something into parts. It can be used for physical separation, for dividing tasks, or more abstractly to distinguish or segregate elements.

In use, trennen often requires a direct object, for example: du trennst den Müll (you separate the trash) or du trennst Materialien in Kategorien (you separate materials into categories). It can also be used reflexively in the expression sich trennen, meaning to part ways with someone or to separate oneself from something, as in du trennst dich von einer Gewohnheit or sie trennt sich von ihrem Partner.

Conjugation in the present tense shows the form du trennst among other forms: ich trenne, du trennst, er/sie/es trennt, wir trennen, ihr trennt, sie trennen. The verb is regular in its endings, with the second-person singular form ending in -st.

Grammatical notes: trennen is a standard verb and can occur with prefixes to create other verbs, such as abtrennen (to detach). In main clauses with separable prefixes, the prefix often moves to the end: du trennst das Kabel ab. The noun corresponding to the action is die Trennung (the separation); the adjective corresponding to the result is getrennt (separated).

Etymology traces back to Old High German trennan and related Proto-Germanic roots meaning to tear apart, reflecting the core sense of dividing or separating something into parts.
