Etymology
The compound "short-turn" is a modern English formation, combining two native Germanic and Latinate roots to create a specific technical term. The adjective "short," with its Proto-Germanic root for curtailed length, modifies the action noun "turn," which evolved from the Latin concept of circular motion on a lathe. In public transport, this literal combination logically describes a vehicle's abbreviated route where it "turns" back prematurely. The financial sense extends this spatial metaphor to temporal brevity, where a "turn" in the market is exploited over a "short" duration.
