fusionnés

Fusionnés is the masculine plural form of the past participle of fusionner, the French verb meaning to merge or fuse. Used as an adjective or as a past participle in compound tenses, fusionnés describes entities that have been brought together into a single unit, such as companies, municipalities, or materials that have been fused.

In grammar, fusionnés agrees in gender and number with the noun it modifies. When used with the auxiliary avoir in a compound tense, the participle generally does not agree unless a direct object precedes the verb. For example: "Des sociétés fusionnées" (merged companies) or "Les pièces fusionnées par soudure" (the pieces fused by welding). In a passive or adjectival sense, one might also encounter forms like "la commune fusionnée" or "les communes fusionnées," depending on the noun involved.

Common contexts for the term include business and administration, where mergers are routinely described as "fusion des sociétés" or "sociétés fusionnées." In local government in France, the word historically described municipalities that have merged; in practice, many mergers now result in the creation of a "commune nouvelle," a status that has largely supplemented or replaced older usages of fusionnée for administrative units.

Beyond administrative usage, fusionnés can also refer to physical or chemical fusion processes, or to any situation in which separate elements have been combined into a single whole, such as metals fused together or datasets merged in data processing. The term thus covers both linguistic usage and a range of practical merging operations.
