3 syllables: fi, bro, sis. Stress on bro.
feye-BROH-suhs
/faɪˈbɹoʊsəs/
fibrosis is pronounced feye-BROH-suhs (/faɪˈbɹoʊsəs/). It has three syllables (fi-bro-sis), with the stress on "bro". Fibrosis is the formation or development of excess fibrous connective tissue in an organ or tissue, typically as part of a reparative or reactive process. It often results from chronic injury or inflammation and can lead to scarring and impaired function. In medical contexts, fibrosis is used to describe pathologic tissue change that disrupts normal architecture and performance.

Tips: slow the transition from /br/ to the final /s/ so there’s no extra vowel inserted. Practice with minimal pairs like fibrosis vs fibrous and observe the exact vowel quality in the middle syllable.
"Pulmonary fibrosis can reduce lung capacity over time."
"Hepatic fibrosis indicates progressive scarring of the liver due to chronic liver disease."
"The biopsy showed cardiac fibrosis, suggesting prior myocardial injury."
Pronounce as faɪ-ˈbroʊ-səs in US, or faɪ-ˈbrəʊ-sɪs in UK. The key is the second syllable: BR-O or BR-əʊ, with stress on the second syllable (bro). The final -sis sounds like səs in many US contexts and sɪs in some UK variants. mouth: start with f as a labiodental fricative, then a long i, then a stressed 'bro' or 'brəʊ', and finish with a light 'səs' or 'sɪs'.
Common errors: misplacing stress on the first syllable (faɪ-BRO-sɪs vs faɪ-bro-SIS), pronouncing the second syllable as 'breeze' style or turning -sis into -sis with a hard 'z' instead of a softer 's' or 'z' blend, and confusion between US 'səs' vs UK 'sɪs' endings. Correction: keep stress on the second syllable: faɪ-ˈbroʊ-səs (US) or faɪ-ˈbrəʊ-sɪs (UK); end with a reduced schwa in US or a crisp -sɪs in UK, and ensure the 'br' cluster is tightly produced without adding extra vowels.
In US, the ending tends toward -səs with a reduced final vowel, and the middle vowel is a long o in -broʊ-. In UK, the middle vowel shifts to a closer -brəʊ- with less lip rounding, and the ending may be crisper -sɪs. Australian tends to be closer to US but with more centralized vowel qualities; you may hear a slightly shorter first vowel after f and a more clipped -brəʊ-sɪs. Overall, the main differences are rhotics, diphthong quality in the second syllable, and final vowel length.
Three challenges: (1) the two consecutive consonants in -br- can create a tricky onset cluster; keep the /br/ together without inserting an extra vowel. (2) The second syllable contains a stressed diphthong in US (broʊ) or a diphthong-like vowel in UK (brəʊ), which can be easy to flatten. (3) The final -sis ends with an unaccented syllable that often reduces to a schwa or a short s sound; avoid over-pronouncing it. Practice with a focused mouth position to stabilize /br/ and the final /s/.
A distinctive feature is the strong second syllable onset with the liquid /r/ followed by a rhotacized or rounded vowel, which impacts lip rounding and jaw position. US tends to have a full /oʊ/ or /oʊ/ quality in the second syllable, UK favors a more centralized /əʊ/ or /əʊ/ with less lip rounding, and AU often sits between US and UK. Keeping the /br/ cluster cohesive is essential for natural rhythm.

US: /faɪ-ˈbroʊ-səs/ with a clear /oʊ/ in the second syllable; UK: /faɪ-ˈbrəʊ-sɪs/ with /əʊ/ and crisper final /ɪs/. AU: often closer to US, but you may hear a slightly shorter /oʊ/ and a less pronounced final vowel. Vowel notes: -ɪ in final -sis can be reduced to ə or sɪs depending on speed; keep final /s/ soft and unvoiced. Consonants: ensure /f/ is labiodental, /br/ is a tight plosive-derived cluster, avoid inserting vowel between /b/ and /r/. Rhoticity: US /r/ is pronounced; UK/AU may be non-rhotic; this may affect the preceding vowel quality.
Fibrosis comes from the Latin word fibra meaning fiber, and the suffix -osis indicating a process or condition. The term entered medical Latin as fibra with -osis to denote a pathological process involving fibrous tissue formation. The root fibra traces to Greek s, which historically described thread-like structures; the concept of fibrous tissue as a scaffold or reparative element is ancient in anatomy. Through the 19th and 20th centuries, fibrosis was adopted to describe granulation tissue forming scar tissue in organs, particularly in pathology and radiology reports. The distinction between normal reparative fibrosis and pathological fibrogenesis evolved with modern histology, recognizing excessive deposition of collagen by fibroblasts as the hallmark. First known uses appear in medical texts in the late 1800s as pathology descriptions, then expanding in the 20th century with emphasis on systemic fibrotic diseases like pulmonary fibrosis and hepatic fibrosis. Today, fibrosis is a standard term across cardiology, pulmonology, hepatology, and nephrology, describing chronic scarring processes that alter organ architecture and function.
