fusionnées

Fusionnées is the feminine plural form of the French past participle fusionné, derived from the verb fusionner. It is used as an adjective or in compound tenses to indicate that several elements have been joined into a single unit. It contrasts with the masculine forms fusionné (singular) and fusionnés (masculine plural), and is commonly found in formal or technical writing.

Grammatically, fusionné agrees with the noun it describes. In passé composé with the auxiliary avoir, the participle generally does not agree unless the direct object precedes the verb. For example: j’ai fusionné les pièces (no special agreement), whereas les pièces que j’ai fusionnées shows feminine plural agreement because the direct object precedes the auxiliary. As an adjective, des pièces fusionnées describes pieces that have already been fused.

Common domains where fusionnées appears include business, science, and data processing. In business or legal contexts you will encounter sociétiés ou entreprises fusionnées to denote merged companies. In biology or materials science, cellules fusionnées or composants fusionnés describe cells or components that have merged. In information science and data integration, données fusionnées refers to data that have been combined from multiple sources.

Étymologie: fusionnées comes from fusionner, itself built on the noun fusion, which traces back to Latin roots related to fusion and fundere (to pour, melt together). The form fusionnées specifically marks feminine plural agreement in contexts where the described items are feminine and plural.

In summary, fusionnées signals that multiple elements have been merged and is used across several technical and descriptive domains to convey that sense of fusion or merging.
