/ˌkævɪˈteɪʃən/
cavitation is pronounced kav-it-AY-shuhn (/ˌkævɪˈteɪʃən/). It has four syllables (cav-i-ta-tion), with the stress on "ta". Cavitation is the formation or presence of vapor-filled cavities in a liquid, typically caused by rapid changes in pressure. It can also refer to the process of creating such cavities in mechanical systems, which can lead to erosion. The term is often used in engineering and physics contexts, especially in fluid dynamics and ultrasonic applications.

"The high-frequency ultrasound treatment relies on cavitation to disrupt targeted tissues,"
"Engineers study cavitation to prevent damage to ship propellers and turbines."
"Cavitation bubbles collapse violently, releasing energy that can affect nearby surfaces."
Cavitation is pronounced kah-vi-TAY-shun in US and UK practice, with primary stress on the second syllable: /ˌkævɪˈteɪʃən/ in US-like notation. Break it as cav-i-tion, where the first syllable sounds like 'cav' (rhymes with 'have'), the middle as 'i' (short i), and the stressed 'ta' sounds as 'tay' before the '-tion' ending. In careful speech you’ll hear the clear /ˈteɪ/ in the third syllable; the final 'tion' is 'shən' /ʃən/. For audio reference, you can listen to standard medical science pronunciations on medical dictionaries or Forvo. Practice: cav-ih-TAY-shuhn with smooth linking between syllables.
Common errors include misplacing the stress (say-ing cav-ah-TA-shun) and mispronouncing the middle vowel as a short ‘i’ in -vi- instead of a clear /ɪ/ in US rhythm. Another frequent slip is turning the final -tion into a full ‘n’ or ‘shun’ without the expected /ʃən/ sound, or adding an extra syllable like /ˌkævɪˈteɪʃən/ with an unnecessary second syllable. Correct by reinforcing the /ˌkævɪˈteɪʃən/ pattern, emphasizing the 'ta' as 'ts'—well, ‘tay’—and finishing with a light, unstressed /ən/. Use slow, exaggerated practice and then reduce to natural tempo.
In US, UK, and AU, the word shares primary stress on the second syllable, but rhotics and vowel quality differ. US typically has /ˌkævɪˈteɪʃən/ with rhotic influence slightly raising the /ɹ/ in related words; the UK variant /ˌkævɪˈteɪsən/ would lean toward /-tɪən/ vs /-teɪʃən/ depending on speaker, and Australian English tends to be non-rhotic with more vowel centralization in the final syllable; overall the stressed /ˈteɪ/ is maintained. Listen for subtle vowel shifts in the first syllable and the final unstressed -tion often realized as /ʃən/ in all three, though some regions may soften to /sən/. IPA: US /ˌkævɪˈteɪʃən/, UK /ˌkævɪˈteɪʃən/, AU /ˌkævɪˈteɪʃən/.
The main challenge is the sequence of consonant and vowel sounds in quick succession: the /k/ plus /æ/ plus /v/ can blur if you don’t separate the /v/ from the initial /k/; the stressed /teɪ/ has a long vowel that can tilt toward /ti/ if you’re not careful; and the final /ʃən/ requires a light, almost swallowed /ən/. Mastery comes from accurate tongue positioning for the /k/ release, clean mid-vowel /æ/ versus a more centralized /ə/ in fast speech, and precise /ˈteɪ/ producing a crisp, loud peak before /ʃən/.
Because cavitation involves rapid pressure changes that create and collapse bubbles, people often ask about the term itself; the unique feature is the transition from a closed cavity concept to dynamic gas-liquid interfaces. You’ll often see it paired with ‘bubble dynamics’ or ‘cavitation inception’ in technical texts. Pronunciationally, ensure the primary stress remains on -teɪ- and the ending -ʃən is soft, not over-emphasized. The word’s anatomy—/kævɪ/ + /ˈteɪ/ + /ʃən/—helps you anchor mouth shapes across contexts.

Cavitation derives from the Latin cavus, meaning 'hollow' or 'cave,' plus the suffix -ation, forming a noun that denotes the condition or process. The earliest English use appears in scientific literature from the 19th century as fluid dynamics and hydraulics matured; it referred to the creation of cavities (bubbles) in liquids under varying pressure. The term captures the physical phenomenon of bubble formation due to local pressure drops and the subsequent implosive collapse, which releases energy. Over time, cavitation has become central in many disciplines: naval engineering (propeller erosion), hydraulic machinery, ultrasonic medicine (biomedical imaging and therapy), and sonochemistry (reactions driven by bubble dynamics). The word’s sense broadened from general ‘cavity formation’ to a precise mechanical/physical process with measurable parameters like cavitation number, Reynolds number, and bubble dynamics. Intense research in the 20th and 21st centuries refined the concept into regime maps, collapse strength estimations, and diagnostic techniques, reinforcing cavitation as a universal fluid-dynamic phenomenon with both beneficial and detrimental applications. First known use in English records surfaces in technical writings in the late 1800s, and the word has since tracked the evolution of experimental and computational tools used to visualize and quantify bubble behavior in liquids under pressure fluctuations.
