ausgebauten

Ausgebauten is a German word form derived from the verb ausbauen, meaning to expand, develop, or build out. As a past participle used as an adjective, ausgebaute or ausgebauten describes something that has been expanded or developed. The ending -en appears in several common declension patterns, especially in plural or feminine singular dative constructions, and in noun phrases without a preceding article.

Etymology and grammar: The base participle is ausgeba(u)t, formed from prefix aus- and bauen (to build). When used attributively or predicatively as an adjective, it is declined to agree with the noun in gender, number, and case. Examples include die ausgebauten Straßen (the expanded roads, plural, nominative/accusative), mit ausgebauten Straßen (with expanded roads, dative plural), der ausgebauten Straße (the expanded road, feminine singular dative), and das ausgebauten Gelände (ambiguous but illustrates the pattern with neuter nouns in certain cases).

Usage and contexts: The form appears mainly in contexts related to infrastructure, urban planning, architecture, or descriptive reporting. It conveys that an object has undergone development, enlargement, or modernization, such as roads, rail lines, facilities, or spaces.
