What Caribbean word does barbecue come from?

The word "barbecue" doesn't come from a Caribbean word. It actually comes from the Taíno language, spoken by the indigenous people of the Caribbean islands. The word "barbacoa" referred to a framework of sticks used for smoking and roasting meat.

This practice of smoking and roasting meat on a raised framework, using green wood for flavor, was adopted by the Spanish colonizers and eventually spread to other parts of the world, evolving into the "barbecue" we know today.
