Etymology: "Outflux" is about as transparent as English compounds get: it is simply "out-" attached to "flux." The prefix "out-" comes from Old English "ūt," meaning outward or away from within, and it has been used productively in English for centuries to form words like "outburst" or "outgrowth." The second element, "flux," comes from Latin "fluxus," the past participle of "fluere," meaning "to flow," which also gave English "fluid," "influence," and "affluent." Put together, the two parts describe a flowing out, so an outflux is the movement of something outward from a place, whether that is a stream of people leaving a city, money draining from an economy, or energy radiating from a source. Its meaning is literal in the way its parts suggest, and the compound reads as a plain description of what it names.
