Unterscheidest

Unterscheidest is the second-person singular present indicative form of the German verb unterscheiden, meaning to distinguish or differentiate. It is used when addressing one person informally as you. For example, in a sentence like Du unterscheidest zwischen Wahrheit und Meinung, the speaker indicates you distinguish between two concepts. The base verb appears in all standard present-tense forms: ich unterscheide, du unterscheidest, er unterscheidet, wir unterscheiden, ihr unterscheidet, sie unterscheiden. The past participle is unterschieden, and the present perfect is formed with haben: Ich habe unterschieden.

Unterscheiden is formed from the root scheiden (to separate) with the prefix unter-, yielding the sense of making distinctions within a set of items or concepts. The noun form is Unterscheidung, meaning a distinction or differentiation; related nouns include Unterschied, meaning difference. The verb belongs to the broader family of German verbs that express separating or differentiating actions.

Usage notes and examples: unterscheidest typically governs a direct object or a prepositional phrase such as zwischen (between). Common constructions include zwischen A und B unterscheiden (to distinguish between A and B) or sich von etwas unterscheiden (to differ from something). The form du unterscheidest is standard in everyday speech and writing when addressing one person informally.
