Während
Während is a German word that functions primarily as a subordinating conjunction meaning "while" or "during." It introduces clauses that express temporal relationships or, in some contexts, contrast. When it introduces a subordinate clause, the finite verb generally appears at the end of that clause, as in: Während ich koche, höre ich Musik.
As a preposition, während governs the genitive: während des Meetings, während der Pause. This use means "during"
Usage notes and examples: The conjunction use can express simultaneity or contrast between two situations. Examples:
