emparelhar

Emparelhar is a Portuguese verb that denotes making two elements form a matched pair or operate as a unified unit. The action can refer to physical coupling, such as aligning gears or connectors so they mesh, or to establishing a functional link between devices, systems or subsystems, for example pairing a smartphone with a headset or a computer with peripherals. The related noun is emparelhamento, and the participles include emparelhado (paired) and gerund emparelhando (pairing).

In technical and engineering contexts, emparelhar describes configuring components to work together. Examples include emparelhar engrenagens to ensure proper meshing, emparelhar sensores with a controller, or emparelhar interfaces in a mechanical system to achieve synchronization. In information technology and consumer electronics, emparelhar is commonly used to refer to connecting devices for communication or data exchange, such as emparelhar dispositivos via Bluetooth or other wireless protocols. In these domains, parear is a widely used synonym, and emparalhar is often considered a more formal or register-specific variant.

The term can also appear in general or informal speech to indicate forming a couple or pairing with another person, though this social usage is less common and may vary by region. Related terms include parear (especially in the context of device pairing) and acoplar (to couple or connect, with broader mechanical connotations).
