Jetted

Jetted is an English term that functions as both a verb form and an adjective. As the past tense of jet, it refers to movement or propulsion produced by jet engines or by jets of water, air, or other fluid streams. For example, a jetting action propels a watercraft, or a fountain can jet water into the air.

As an adjective, jetted describes items or features that incorporate jets or jet-like elements. The most common usage is in plumbing and spa contexts: a jetted tub (also called a whirlpool tub) has multiple water jets installed to create a hydrotherapy massage. In fashion, a jetted pocket is a type of slender, slit-like pocket opening edged with welts, typical on tailored jackets and trousers.

In industrial and construction settings, "jetting" or "jetted" can describe processes that use high-pressure jets, such as water jetting to clean surfaces, loosen soil, or cut materials. In aviation, though less common, "jetted" may describe movement propelled by jet engines, as in a jetting aircraft or vehicle.

Etymology: from the noun jet, meaning a stream, projection, or spurting nozzle, with the verb form giving rise to adjectives describing jet-powered or jet-equipped objects. See also jet propulsion, welt pocket.
