4 syllables: Me, ta, sta, sis. Stress on ta.
muh-TAS-tuh-sis
/məˈtæstəsɪs/
Metastasis is pronounced muh-TAS-tuh-sis (/məˈtæstəsɪs/). It has four syllables (Me-ta-sta-sis), with the stress on "ta". Metastasis is the process by which cancer cells spread from a primary tumor to form new tumors in distant sites. It indicates progression of disease and is central to staging and prognosis. The term combines Greek roots referring to change in place and displacement. In medical contexts, it is used to describe metastatic spread rather than localized cancer.

- Common phonetic challenges: the mid-syllable /stæs/ cluster can be rushed or softened; the /æ/ in ‘stas’ can become a schwa, flattening the word’s rhythm. Another pitfall is misplacing the primary stress on an earlier or later syllable, leading to ‘meh-TAS-tis’ feeling incorrect. - Corrections: 1) slow the tempo to feel the metrical beat: /ˌmɛtəˈstæsɪs/, 2) ensure the middle syllable has a clear /æ/—practice with ‘cat’ + ‘siss’ motif to anchor it, 3) end with a crisp /ɪs/ or /əs/ without over-voicing. Practice saying it in alternating loud/soft volumes to feel the pulse. - Practice with tongue positioning: keep the tongue high and forward for /æ/, and avoid tensing the jaw. - Breathe before the stressed syllable to preserve energy for correct articulation.
How to Pronounce Metastasis
"The patient was diagnosed with metastasis to the liver."
"Doctors discussed treatment options for metastatic breast cancer."
"Imaging revealed metastasis in multiple bones."
You say /ˌmɛtəˈstæsɪs/ in American English and /ˌmɛtəˈstæsɪs/ in UK English, with the main stress on the second‑syllable unit ‘tas’ (met-as-TA-sis). Break it as me-TA-sta-sis, where the emphasis sits on the ‘tas’ syllable. The first syllable is a weak 'meh' (schwa), and the middle 'tas' carries the main stress. For audio reference, imagine a clinical enunciation: /ˌmɛtəˈstæsɪs/.
Common errors include stressing the wrong syllable (say ‘meh-TA-sta-sis’ instead of ‘met-uh-STAT-uh-sis’), and mispronouncing the middle 'tas' as ‘tass’ with a short ‘a’ instead of a clear /æ/ as in ‘mass.’ Another frequent slip is over-articulating the final -sis as /sɪs/ rather than /səs/. Correct by emphasizing ‘tas’ with /æ/ and finishing with a light /sɪs/ or /səs/ depending on speaker. Listen for the disyllabic rhythm: met-uh-STAS-is.
In US and UK accents, the word has a similar rhythm, with stress on the second syllable: meh-tuh-STAS-is. The Australian accent can reduce the first syllable to a schwa more quickly and may slightly flatten the final vowel, but the nucleus /æ/ in ‘stas’ remains prominent. Rhoticity affects the preceding vowel’s coloration in some American speakers. Overall the stress pattern is stable; vowel quality varies by accent. IPA references: US/UK /ˌmɛtəˈstæsɪs/; AU /ˌmiːtəˈstæsɪs/ (roughly).
Two main challenges: the multisyllabic rhythm with the mid-word stress on the second strong syllable, and the diphthong-free middle /æ/ in ‘stas’ combined with a final unstressed /əs/ that can blur into /əs/. The sequence /stəˈstæs/ requires precise articulation: a relaxed schwa in the first syllable, a clear /æ/ in ‘stas’, and a crisp final /ɪs/ or /əs/. Practicing with slow tempo and finger-tocalm breath helps center the mouth for accurate timing.
The key nuance is keeping the middle syllable steady with /æ/ and not reducing it to a schwa; some speakers may pronounce ‘tas’ as ‘tahs’ if hurried, which shifts the stress pattern subtly. Focus on a clean /ˈstæs/ cluster preceded by /tə/ and followed by /ɪs/. Visualize the sequence: me-tuh-STAS-is, with a crisp 'STAS' block. Use a mirror to monitor jaw position and ensure the middle syllable is not swallowed by the surrounding vowels.

US: rhotic; r-coloring in nearby vowels may affect transitions but not core syllables. UK: non-rhotic; final r not pronounced, but the /æ/ in ‘stas’ remains clear. AU: generally non-rhotic; tends to have a tighter, slightly clipped final syllable, with a more pronounced schwa in the first syllable. Vowel quality: /ɛ/ in the first syllable is bright in US, slightly backed in some UK and AU speakers. - IPA references: US/UK /ˌmɛtəˈstæsɪs/; AU /ˌmiˈtəˈstæsɪs/ (approx). - Practical tips: exaggerate the middle /æ/ in practice to transfer to natural speech. - mouth positions: lip rounding minimal; jaw relaxed; keep tongue blade high for /t/ and /s/ transitions.
Metastasis comes from the Greek meta- meaning 'change' or 'beyond' and -stasis meaning 'standing, placed, position' (from Stasis). The term evolved from ancient Greek medical descriptions by early anatomists who observed tumors appearing in locations other than their origin. In 19th-century medical literature, metastasis began to denote the process by which cancer cells spread through lymphatic or hematogenous routes to distant sites. The concept solidified with advances in pathology and imaging, enabling clinicians to distinguish primary tumors from secondary growths. The word entered English medical vocabulary through transliterations of Greek-rooted terms in early modern medicine, with first known usages appearing in 1800s oncology texts, and becoming standard by the 20th century as understanding of cancer biology expanded.
