2 syllables: throm, bus. Stress on throm.
/ˈθrɒmbəs/
thrombus is pronounced /ˈθrɒmbəs/. It has two syllables (throm-bus), with the stress on "throm". A thrombus is a blood clot formed within a blood vessel or the heart, potentially obstructing flow. It can originate in arteries or veins and may lead to serious complications if dislodged. The term is used in medical contexts to describe the solid mass that results from the coagulation of blood components at a site of vessel injury or abnormal flow.

"The patient developed a thrombus in the deep leg veins after extended bed rest."
"A thrombus in the coronary artery can cause a heart attack if it blocks blood supply."
"Doctors prescribed anticoagulants to prevent new thrombi from forming."
Pronounce it as ˈθrɒm.bəs in UK and US; AU often uses ˈˈθɹɒm.bəs with an approximant r. The primary stress is on the first syllable: THROM-bus. Start with a voiceless dental fricative θ (as in think), then r, then short a as in ‘lot’ or ‘not’ depending on accent, followed by m, and end with bəs where the -bus sounds like ‘bus’ with a short schwa before s. IPA: US/UK: θrom.bəs; AU: θɹɒm.bəs. Listen to medical diction audio to confirm subtle vowel quality.”,
Common errors: 1) Say ‘throhm-bus’ with long ‘oh’; correct is short ‘o’ as in ‘lot’ (θɒm). 2) Misplacing /r/ or using a hard American /ɹ/ after θ; aim for a light, non-syllabic r in non-rhotic styles. 3) Dropping the final syllable or turning it into ‘throm-buss’ with extra s; keep final schwa before s: -bus (bəs). 4) Substituting /θ/ with /f/ or /t/; use the dental fricative θ. Practice with minimal pairs like ‘throb’ vs ‘throm’ to feel the contrast.”,
In US/UK, the initial θ is pronounced with the dental fricative; rhoticity varies by context, but the /r/ in throm- is typically pronounced in rhotic accents. US tends to have a quicker, more rounded vowel in the second syllable; UK often features a shorter, clipped -bus and less rhotic vowel shift. In Australian English, /θ/ remains the same, the /ɹ/ is less retroflexed and the vowel in the first syllable may approach [ɒ] or [ɔ] depending on speaker. Overall, US tends to be rhotic and flatter, UK less rhotic, AU somewhere in between; the crucial differences are vowel quality and r-coloring after the first syllable. IPA references: US θɹɒm.bəs, UK θɒm.bəs, AU θɹɒm.bəs.
It combines a voiceless dental fricative /θ/ with a velar or alveolar stop, then a rapid /r/ sequence followed by a short unstressed /ə/ in the second syllable. Many speakers mispronounce the initial /θ/ or replace with /f/ or /t/. The stress on the first syllable makes it easy to flatten the second, but you should maintain a clear, short schwa in the second syllable. Also, some speakers mispronounce /bəs/ as /bus/ with a full vowel; keep it as /bəs/ with a schwa before the s.

Thrombus comes from the Late Latin thrombus, from Greek thrombós, meaning 'clot, slab, lump,' related to thrombosis, from thrombos ‘lump, clot’ and -osis indicating a pathological process. The Greek root thromb- stems from thromma ‘a lump or clot.’ The term migrated into medical Latin with early usage in the 19th century as anatomy and physiology terminology standardized. Over time, thrombus retained its core meaning as a solid mass formed by aggregation of platelets, fibrin, and blood cells in vivo. It distinguished from embolus, which refers to a detached thrombus traveling through the bloodstream. First known English uses appear in medical writings in the 19th century as clinicians described intravascular occlusions, and the word has since become a staple in hematology, vascular medicine, and radiology reports.
