Verschlüssen

Verschlüssen is the dative plural form of the German noun Verschluss, which broadly denotes a closure, lid, seal, or fastening device. In German sentences, Verschlüsse refers to the plural nominative, while Verschlüssen appears after definite or indefinite articles and prepositions that require the dative case, as in mit den Verschlüssen (with the closures).

The term Verschluss has several related senses. In mechanical engineering and construction, it designates any device that seals or locks a component, such as a valve, hatch, door, or cap. In packaging and transport, it can refer to closures that seal containers to protect contents. The word also appears in compound terms like Türverschluss (door lock) or Deckelverschluss (lid fastener). Etymologically, it is derived from verschließen, meaning to close or seal, and shares roots with related words for sealing and locking.

In usage, Verschlüssen is encountered primarily in technical or formal prose. It appears when listing or describing multiple closures in the dative context, for example: Die Anlage ist mit den Verschlüssen gegen unbefugten Zugriff gesichert. Another example: Die Tür ist mit den Verschlüssen versehen. In everyday speech, speakers more often use the nominative Verschlüsse or specific compound names, but Verschlüssen remains correct in grammatically appropriate phrases.
