The word 'beam' refers to a long, sturdy piece of wood, metal, or concrete that is used to support a structure, such as a building or a bridge. Beams can be horizontal or vertical, and they are often used in construction to transfer weight or support a load. For example, the ceiling of a room may be supported by wooden beams, or the frame of a house may be reinforced with steel beams. In everyday conversation, the word 'beam' may also refer to a bright and narrow ray of light, such as the beam of a flashlight or a laser pointer.
