Meaning and Definition
A temporary support, often made of wood or metal, used to hold something in position, reinforce a structure, or provide stability during construction, repair, or lifting operations.
The term can refer to the action of using such a support, or to a mechanical device (often a screw jack or hydraulic jack) used in conjunction with bracing for lifting or stabilization. In a figurative, non-technical sense, it can describe any person or thing that provides crucial support in a difficult situation.
