ballast
This term describes a stabilizing force that prevents tipping or drifting, whether through physical weight or psychological grounding. In maritime and engineering contexts, it refers to the strategic placement of heavy materials to lower the center of gravity, ensuring a vessel remains upright in turbulent waters. When used in a psychological sense, it describes a stabilizing influence or habit that keeps a person emotionally balanced during chaos. As a noun, it is typically treated as an uncountable mass when referring to the material itself (like gravel or sand), though it can be countable when referring to specific types or systems of ballast.
