bridar

A technical verb with two narrow uses: in equestrian contexts, to fit a horse with a bridle (poner la brida), and in mechanical/plumbing contexts, to join two pipes or parts with a flange (brida). Not an everyday verb — most speakers would use the near-synonym embridar for the equestrian sense or simply describe the mechanical action.

• El mozo de cuadra bridó al caballo antes de la salida. — The stable hand bridled the horse before setting out.
• Bridaron las dos secciones de tubería en la obra. — They flanged the two sections of pipe together on the job site.
• Hay que bridar bien la manguera para que no se suelte. — The hose needs to be properly clamped so it doesn't come loose.

This is specialist vocabulary — outside a stable or a workshop, a learner is far more likely to need or hear embridar (horses) or unir/acoplar (pipes/parts) in everyday speech.
