Etymology
The compound term "stop-loss" is a modern financial construction built from two foundational Germanic words. "Stop" originates from the Old English stoppian, meaning to block or plug, which itself has probable Latin influence from stuppāre, "to stop with tow." "Loss" derives from Old English los, meaning destruction or ruin, related to the verb lēosan, "to lose." The term's logic is transparently literal: it is an instruction to stop an ongoing loss. In the 20th century, it was adopted into brokerage terminology to denote a preventative order, perfectly encapsulating its core function of halting financial decline at a predefined threshold.
