tillsluten

Tillsluten is a Swedish adjective and past participle of the verb tillsluta, meaning closed off, sealed, or blocked. It describes something whose opening has been closed so that passage or access is prevented. The term can apply to physical closures—such as a door, valve, container, or passage that has been sealed—as well as to figurative closures, like information, access, or a process that has been restricted.

In use, tillsluten can describe both concrete objects and abstract situations. For example, a door may be tillsluten (sealed shut) or a corridor may be tillsluten off from other areas. In legal or administrative language, information or documents can be tillsluten, indicating restricted or sealed access. The form is commonly used attributively, as in tillsluten dörr or tillsluten behållare, with the definite form adapting to grammar like any Swedish adjective.

Etymology and grammar: tillsluten derives from tillsluta, itself a compound of till (to) and sluta (to close). As a past participle used as an adjective, tillsluten agrees with the noun it modifies in number and definiteness.

Related terms include tillsluta (to seal off or close), and the noun tillslutning (the act of sealing off or the state of being sealed). Synonyms or near-synonyms in Swedish include stängd, igensluten, and försluten, depending on context.
