basés

Basés is the masculine plural past participle of the French verb baser, used as an adjective meaning based, located, or founded. In modern French, it most often indicates where an organization or person is located, or describes information or conclusions that derive from a source. When applied to a noun, basés agrees in gender and number with that noun.

Grammar and usage: The forms are basé (masculine singular), basée (feminine singular), basés (masculine plural), basées (feminine plural). When describing location, it is typically used with être: “L’entreprise est basée à Paris.” With plural nouns: “Les entreprises sont basées à Paris.” When indicating basis, the construction is often “basé sur” (masculine singular) or “basés sur” / “basées sur” depending on the noun: e.g., “Des conclusions basées sur des preuves.”

Notes on translation and nuance: Basé can also function as a past participle with avoir in transitive use, in which case the participle may agree with a preceding direct object, for example: “Les décisions que j’ai basées sur les faits” (basées). The phrase “basé sur” is widely used in business, journalism, and academic writing to mean “based on.” In English, it is commonly rendered as “based (in/located)” or “based on,” depending on the sense.
