röret

Röret is the definite singular form of the Swedish noun rör, which denotes a hollow cylinder used to convey liquids or gases or to serve as a conduit in plumbing, heating, ventilation, and various kinds of machinery. The term covers a broad range of objects, from small plastic tubes to large metal pipes, and can be found in domestic settings, construction, and industry.

In everyday language, röret appears in compound terms describing specific pipes, such as avloppsröret (drain pipe), vattenröret (water pipe), gasröret (gas pipe), and kabelröret (cable conduit). It also shows up in technical drawings, manuals, and specifications where a particular pipe is identified. For example, Röret i källaren läcker. The form is used when referring to a specific pipe that both speaker and listener know about.

Grammatical note: The indefinite singular is rör, the definite singular is röret; the indefinite plural is rör, and the definite plural is rören.

Etymology and cognates: The word rör originates from the broader Germanic language family, with cognates in Norwegian (rør) and Danish (rør). These forms reflect a common linguistic heritage across Scandinavian languages and similar terms used for tubes and pipes.
