baserad

Baserad is a Swedish adjective meaning “based” or “based on.” It describes something that has its basis in a source, method, or principle, and is commonly used to indicate how a claim, narrative, or decision is grounded. The term appears frequently in journalism, film, academia, and everyday language, for example to specify what a work is based on.

Grammatically, baserad agrees with the noun it modifies. Typically baserad is used with feminine singular or common gender singular nouns, baserat with neuter singular nouns, and baserade with plural nouns. Examples: En bok baserad på verkliga händelser. Ett beslut baserat på fakta. Flera filmer baserade på verkliga berättelser.

The verb from which it derives is basera, meaning “to base.” Basera is a regular -a verb: present baserar, past baserade, supine baserat. In phrases like Filmen baseras på en sann historia, baseras expresses a passive or source-based relation rather than a simple predicate.

Etymology-wise, basera comes from the noun bas (base/foundation). The root is related to basis in many languages, and the suffix -era forms the verb. The participle baserad functions as the adjectival form used to describe something that has its basis in a source or reference.

Related terms include bas, basbygge, grund, and grundad, which convey concepts of foundation or grounding. In translation, baserad is most commonly rendered as “based on” in English, as in “a film baserad på en sann historia.”
