Appareiller

Appareiller is a French verb with several related senses tied to the idea of preparing, equipping, or setting in motion equipment or vessels. Etymologically, it derives from appareil, meaning equipment or apparatus, with the -er verb suffix.

In nautical usage, appareiller means to depart from port or to set sail. It describes the act of a ship leaving to begin a voyage. For example, “Le navire appareille à l’aube.” This sense emphasizes readiness and initiation of a journey.

In technical and industrial contexts, appareiller can mean to equip, outfit, or wire up equipment or instruments so they are ready for operation. It covers tasks such as assembling components, wiring systems, or integrating devices within a broader setup. For instance, “appareiller des instruments sur le banc de test” indicates preparing and connecting instruments for testing.

In a more general sense, the term can also denote provisioning or fitting with necessary equipment, materials, or hardware, especially in manufacturing or logistics settings. The noun compatible with this use is appareillage, referring to the set of equipment or hardware itself.

Conjugation and usage notes: appareiller is a regular -er verb. Main forms include j’appareILLE, tu appareilles, il appareille, nous appareillons, vous appareillez, ils appareillent. In contemporary everyday French, the sense “to pair devices” is more commonly expressed with other verbs such as appairer or accoupler, depending on the context.
