Basâ

Basé is the past participle of the French verb baser. It is used as an adjective or participle meaning “based” or “grounded,” and it agrees in gender and number with the noun it modifies: masculin singulier basé, féminin singulier basée, masculin pluriel basés, féminin pluriel basées. It appears most commonly in two constructions: basé à to indicate location or affiliation, and basé sur to indicate a basis or source.

Examples include: “L’entreprise est basée à Paris.” “Le film est basé sur une histoire vraie.” The phrase “basé à” is used for organizations or people to state their location, while “basé sur” marks the basis of a claim, story, or analysis.

Grammatical notes: In a passive sense or with the auxiliary être, the participle agrees with the subject, as in “L’équipe est basée à Lyon.” In phrases like “des données basées sur…” it functions adjectivally and agrees with the noun it describes (basées for feminine plural, basés for masculine plural).

Etymology and synonyms: Basé derives from the verb baser, itself linked to the notion of a base or foundation. Depending on context, related expressions include “fondé sur,” meaning “founded on,” or “situé à,” meaning “located in/at.”
