Absperr

Absperr is a bound morpheme in the German language used to form words related to blocking off, closing, or isolating something. It derives from the verb absperren, meaning to block off or seal. As a standalone headword it is not commonly used in ordinary prose; instead, Absperr appears as a prefix or root in compound nouns and adjectives that name devices, areas, or procedures involved in isolation or access control.

The combining form Absperr is found in a range of technical terms. Examples include Absperrventil (shut-off valve), Absperrpfosten (barrier post), and Absperrband (barrier tape). The related noun Absperrung denotes a barrier or act of closing off, while Absperrbereich refers to a restricted area. In safety signage and construction or event management, these forms help specify mechanisms or regions that must be blocked or kept separate.

Usage context for Absperr compounds is common in German-speaking engineering, transportation, construction sites, and emergency response planning. The term often appears alongside other safety and control vocabulary, such as Sperrung (closure) and Absperrung, to describe procedures, equipment, or designated zones that restrict access or separation.
