Fertigst

Fertigst is the second person singular present tense form of the German verb fertigen, meaning to manufacture, produce, or craft. It is used when addressing someone informally with the subject du.

In standard conjugation, fertigen is a regular weak verb. Its present tense forms are: ich fertige, du fertigst, er fertigt, wir fertigen, ihr fertigt, sie fertigen. Therefore, fertigst corresponds to “you manufacture” or “you are manufacturing.” The form is not used with the separable-prefix verb fertigstellen, which means to complete or finish something. With fertigstellen the finite forms are built from the main verb stellen and the prefix ferti- becomes part of the verb’s meaning, as in ich stelle fertig, du stellst fertig, er stellt fertig, and so on. In those constructions the prefix moves to the end in main clauses, while fertigst remains tied to fertigen.

Usage notes and examples: Du fertigst heute neue Bauteile. Sie fertigt handgefertigte Produkte. In contexts that describe finishing a task, native speakers typically use fertigstellen and say du stellst das fertig or ich stelle das fertig.

Etymology and related terms: fertigen derives from the adjective fertig (ready) and the verb ending -en, forming a verb that means to make or produce something to a finished state. Related verbs include herstellen (to manufacture/produce), produzieren (to produce), and anfertigen (to craft or prepare, often with a specific end product).

In summary, fertigst is a standard present-tense form for du with fertigen, while fertigstellen is a distinct verb pair with a different conjugation pattern.
