ballast

What does "ballast" mean?
Ballast refers to heavy material, such as gravel, sand, or water, placed in the hull of a ship or the gondola of a balloon to provide stability and control. Mentally, visualize a ship riding too high on the water and becoming unstable; the ballast acts as a literal anchor of weight that keeps the vessel steady against wind and waves. In a figurative sense, ballast describes something that provides emotional or intellectual stability. You might say that a calm friend acts as "ballast" during a stressful period, keeping you grounded. It is a somewhat formal term, often used in nautical, engineering, or literary contexts to describe the weight necessary to maintain balance.
