A person who falls or responds in opposition to another, or one who opposes or resists something that is falling or declining.
From counter- + faller (from Old English feallan, meaning 'to fall'). A rare term with unclear modern usage, possibly related to forestry or physical resistance.
In logging, a counterfaller might be a worker who prevents a falling tree from crushing equipment—it's a dangerous job that requires timing, strength, and understanding physics to direct the inevitable fall safely.
