Aufgebauten

Aufgebauten is the inflected form of the German past participle aufgebaut, derived from the verb aufbauen (to build, to construct). In everyday German it functions as an adjective describing something that has been constructed or built up. Like other participles used as adjectives, aufgebaut can occur attributively before a noun and is declined to match the noun’s gender, number, and case. The form aufgebauten appears in several common contexts, particularly after definite determiners, where adjectives take weak endings.

Examples include: Die aufgebauten Brücken wurden repariert. Den aufgebauten Turm sieht man von weitem. Die aufgebauten Strukturen sind stabil. In plural nominative: Die aufgebauten Türme prägen das Stadtbild. In dative masculine singular: dem aufgebauten Turm. In feminine dative: der aufgebauten Brücke. After indefinite articles or without determiners, other endings occur: ein aufgebautes Gebäude is neuter singular with -es.

Meaning and usage: The core meaning is built or constructed, with possible metaphorical senses such as well-established or developed. In English translations the word is usually rendered as built-up, constructed, or well-established, depending on context. It is not a separate lexical item; Aufgebauten is simply the declined form of aufgebaut used in noun phrases with different determinations and cases.
