cavitation
UK[ˌkævɪˈteɪʃn]US[ˌkævɪˈteɪʃn]
n
The formation of an empty space within a solid object or body of liquid, especially the formation of bubbles in a liquid when the pressure is reduced.
n
The pitting or erosion of a solid surface, such as a ship's propeller or a pump, caused by the collapse of such bubbles.

Etymology
The word cavitation is a modern scientific term built directly from Latin components. Its core is the Latin root cav-, meaning "hollow," which descends from the Proto-Indo-European keuə-, "to swell" or "to be vaulted," a root that also gives rise to words like "cave" and "cavity." The suffix -itate forms a verb meaning "to make hollow," and the final -ation nominalizes the process. Thus, the literal construction "the process of making hollow" perfectly describes the modern technical phenomenon where rapid pressure changes in a fluid create hollow vapor bubbles, whose subsequent collapse can cause significant physical damage.
Analysis
Structure: cav (hollow) + it (verb suffix) + ation (noun suffix)
- cav: From Latin cavus, meaning "hollow, hole, cavity." Serves as the core root conveying the concept of emptiness or a hollow space.
- it: A Latin-derived verb-forming suffix (as seen in the verb cavitare, "to make hollow"), indicating the action or process.
- ation: A noun-forming suffix of Latin origin (-ationem), indicating the state, action, or result of a process.
Examples
The damaged propeller showed significant wear due to cavitation.
Engineers study cavitation to improve the efficiency of hydraulic pumps.
The intense noise from the pump was a clear sign of cavitation occurring within the system.
