two-stage
Done in halves
Two-stage describes a process or system that operates in two distinct phases, with each phase accomplishing part of the overall function.
A two-stage rocket burns fuel in one section, jettisons it, then ignites a second.
Two-stage triggers require two separate pulls.
Two-stage air compressors compress air twice for higher pressure.
The term appears across engineering, manufacturing, and scientific contexts wherever sequential processing improves efficiency or capability.
