4 syllables: neph, ro, sclero, sis. Stress on sclero.

nephrosclerosis is pronounced nef-ruhs-KLIR-uhs (/ˌnɛfrəˈsklɪrəs/). It has four syllables (neph-ro-sclero-sis), with the stress on "sclero". Nephrosclerosis is a kidney condition characterized by hardening and thickening of renal blood vessels, often due to long-standing hypertension or diabetes. It leads to impaired kidney function as scar tissue develops within the kidney. The term combines the Greek root for kidney (nephro) with sclerosis (hardening), describing progressive vascular and tissue changes.

- You may stumble on the 'phro' vs 'fro' pronunciation; ensure you voice the f sound in the first syllable: nef-ro, not nep-ro. - The 'sclerosis' portion has a dense consonant cluster 'scl', which often gets rushed or swallowed; articulate it clearly as skl-e-rosis, not sk-lor-osis. - Misplacing the main stress; aim for ne-fro-SCLER-osis. - Final '-sis' can be reduced to 'sis' without syllabic clarity; keep the final -ɪs with a crisp s.
"The pathologist noted nephrosclerosis in the renal biopsy of the patient with chronic hypertension."
"Advanced nephrosclerosis can contribute to chronic kidney disease and reduced glomerular filtration rate."
"Kidney imaging suggested nephrosclerosis, correlating with elevated blood pressure and vascular changes."
Break it as nephro- + sclerosis. IPA US: /ˌnɛfroʊˈsklɪrəsɪs/; UK: /ˌnɛfrəʊˈsklɪərəsɪs/; AU: /ˌnɛfrəʊˈsklɪərəsɪs/. The primary stress falls on the third syllable: nefro-SCLI-er-osis. Start with NEF-roh, then SCLIR-, finishing with -uh-sis. Mouth positions: ne- (soft n, open front vowel), phro (lip rounding slight), scl- (cluster with light lip rounding), -er- (schwa), -o- (short o or schwa), -sis (siss). When teaching, emphasize the scl- cluster as a single syllable with a sharp release.
Two frequent errors: misplacing stress so it lands on the wrong syllable (often on -sclerosis rather than -scler-), and substituting a hard e or i in the first syllable (saying ne-FRO-scler- instead of nefro). Correct by practicing the tri-syllabic rhythm: ne-fro-SCLER-os-is, with a clear, brief lift on 'SCLER'. Use small pauses between morphemes if needed to maintain rhythm. Auditory cues: emphasize the scl- cluster early, then glide into -os- and -is. IPA checks: US /ˌnɛfroʊˈsklɪrəsɪs/; UK /ˌnɛfrəʊˈsklɪə.rəsɪs/.
In US English, the first vowel is a tense /oʊ/ in -ro-, and r-colored schwa-like in -er-. UK often uses a slightly more centralized vowel and a longer -ɪə- in -scler- combined with non-rhotic r, leading to /ˌnɛfrəʊˈsklɪə.rəsɪs/. Australian tends to a flatter vowel in -nephro- and slightly longer final -sis, with a less pronounced r in non-rhotic positions. Overall, rhoticity primarily affects the r-coloring of vowels in US speech; UK and AU reduce rhotics in several positions. IPA references show the difference in the 'o' and 'er' vowels.
The difficulty comes from the tri-morphemic construction and the /skl/ consonant cluster. The sequence ne-phro-scleri-sis blends a light schwa, a strong 'skl' cluster, and a final 'sis' syllable that can be mis-timed. The primary stress on the -scler- syllable adds another layer of challenge. To master it, practice the three morphemes separately: nefro-, scler-, -osis, then fuse them with a steady, even rhythm and precise alveolar /s/ and /z/ voice onset times.
A common curiosity is about the 'nephro-' prefix: the 'ph' in 'nephro' is pronounced as 'f' /f/ not 'ph' as in 'pharmacy'. So it sounds like nef-ro, not ne-phro. Also, the 'sclerosis' part has a hard 'scl' cluster that must be clearly released: skl-ER-os-is. Emphasize the second syllable ('scler') while keeping the surrounding vowels soft. The stress pattern is NOT equal across all syllables; the strong emphasis comes on the 'scler' portion.

- US: rhotic, keep /ɹ/ before vowels; stress on 'SCLER'. Vowels tend to be rounded slightly: /ˌnɛfroʊˈsklɪɹəsɪs/; - UK: non-rhotic, may drop post-vocalic r, /ˌnɛfrəʊˈsklɪərəsɪs/; - AU: non-rhotic, flatter vowels, /ˌnɛfrəʊˈsklɪəˌɹəsɪs/ with less pronounced r-coloring. IPA cues: monitor /ɹ/ presence in US, absence in UK/AU; pay attention to /ə/, /ɪə/ sequences in -sclerosis; ensure clear /skl/ cluster. - Vowel quality: /oʊ/ vs /əʊ/ are monophthongs in some speakers; keep consistency.
Nephro- derives from the Greek nephros (kidney). Sclerosis comes from the Greek skleros, meaning hard or hardening. The combination appeared in early medical literature as physicians documented kidney disease associated with vascular and tissue hardening. The term reflects a pathological end-state rather than a single etiologic event; it can arise from long-standing hypertension, diabetes, or other renal vascular insults. First known uses appear in the late 19th to early 20th century, aligning with the rise of modern nephrology when clinicians began classifying kidney pathologies by histological patterns. Over time, nephrosclerosis has been refined to describe both intimal arteriosclerosis of small renal arteries and parenchymal scarring, regardless of the initial trigger. The word's form remains a precise clinical descriptor, though in practice it often appears within broader diagnoses such as hypertensive nephrosclerosis or benign nephrosclerosis. The evolution mirrors shifts in medical understanding from purely descriptive terms to pathophysiologically grounded categories.
