durchgelassene

Durchgelassene is a German term formed from durchlassen (to let through, to admit) and the past participle durchgelassen. It functions primarily as an adjective or, less commonly, as a noun, to denote something that has been permitted to pass through a barrier, filter, gate, or process. In everyday and technical language, it describes items, people, or substances that have been admitted or permeated.

As an adjective, durchgelassene is used before a noun and declines like a normal attributive adjective. Examples include durchgelassene Anträge (applications that have been admitted), durchgelassene Dokumente (documents that were accepted), or durchgelassene Partikel (particles that passed through a filter). The sense is neutral, indicating permission or permeability rather than value judgment. In noun form, the word can be nominalized and capitalized: der Durchgelassene (the one who has been admitted), die Durchgelassene (the admitted person, feminine), die Durchgelassenen (the admitted ones, plural).

Grammatically, durchgelassen is the past participle used to form compound tenses with haben (hat durchgelassen). When used attributively before a noun, it takes appropriate endings: der durchgelassene Antrag, die durchgelassenen Fahrzeuge. If used as a stand-alone noun, it is capitalized and inflected like a regular noun.

Etymology and usage notes: the prefix durch- in durchlassen indicates passage from one side to another, and the term is common in contexts such as border checks, security controls, filtration, and regulatory decisions. It does not imply a value judgment beyond the act of permitting or enabling passage.
