What does cavitated mean?
"Cavitated" is the past tense and past participle of the verb "cavitate," meaning to form cavities or hollow spaces within something. The word belongs chiefly to technical registers. Engineers use it to describe what happens when a liquid's pressure drops sharply enough to create vapor bubbles whose subsequent collapse erodes nearby surfaces — a phenomenon notorious for damaging ship propellers, pumps, and turbines. Dentists apply it to teeth in which decay has progressed beyond softening into an actual hole in the enamel, requiring restoration. In medicine, particularly chest imaging, "cavitated" characterizes lesions such as tuberculous or fungal nodules that have developed a central air-filled space. Derived from the Latin "cavus" (hollow), the term shares its root with "cavity" and "excavate." Though uncommon in casual speech, it is precise and indispensable wherever hidden hollows matter.
verbPast tense and past participle of "cavitate": to form cavities or hollow spaces, especially through the formation and collapse of vapor bubbles in a liquid, or (in dentistry) to develop a cavity in a tooth.
- (Of a liquid or an object moving through it) having undergone cavitation — the formation and violent collapse of vapor-filled bubbles, typically causing erosion of nearby surfaces.
- (Of a tooth) having developed a cavity, i.e. structural breakdown of enamel and dentine forming an actual hole.
"The propeller blades had cavitated badly, pitting the metal surface after years of high-speed operation."
"Dentists confirmed that two molars were already cavitated and would require fillings."
"The pump impeller was so badly cavitated that its efficiency had dropped noticeably."
Cavitated is the word engineers reach for when spinning propellers literally tear themselves apart with bubbles — collapsing vapor pockets can pit metal as if it had been hammered.

Etymology of cavitated
"Cavitated" derives from "cavitate," a verb built on the Latin "cavus," meaning "hollow." The same root produced English "cave," "cavity," "concave," and "excavate," all sharing the sense of hollowness. The verb "cavitate" itself arose in the context of modern physics and engineering, where the phenomenon of cavitation — bubble formation and collapse in moving liquids — was studied from the late nineteenth century onward. Its dental and medical senses extend the same core idea: the creation of a hollow space within a solid structure.

How cavitated is actually used
Predominantly a technical term found in engineering, physics, dentistry, and medical imaging literature. In radiology, "cavitated" describes lesions (especially in the lungs) that have developed central air- or fluid-filled spaces. It is rarely used in everyday conversation; ordinary speakers would say something like "full of holes" instead.
Easily confused with cavitated
"Excavated" means deliberately dug out or unearthed, while "cavitated" refers to hollows formed naturally by bubble collapse, erosion, decay, or pathological processes.
