The word "tubing" derives from "tube," which entered English in the mid-17th century from French "tube" (via Latin "tubus," meaning "pipe"). The suffix "-ing" was added to form a noun, originally describing the material or action related to tubes. By the 20th century, it gained a recreational sense, reflecting the use of inflatable tubes in water/snow activities. The morphemes preserve the original spelling while clearly marking functional boundaries.
