The word 能量 (néngliàng, "energy") is formed through a conceptual fusion of two classical characters: 能, which originally depicted a type of powerful bear and evolved to mean "capability" or "power", and 量, which represents the idea of "measurement" or "quantity". Their combination does not simply add meanings but creates a new, unified scientific concept, the measurable capacity to do work or produce change. This mirrors the way Western science abstracted the Greek word "energeia" (activity) into the physics term "energy", by framing an innate force as a quantifiable physical property. Thus, the formation is a semantic synthesis, building a modern abstract notion from ancient concrete roots.
