2 syllables: vil, lus. Stress on vil.
VIL-uhs
/ˈvɪləs/
villus is pronounced VIL-uhs (/ˈvɪləs/). It has two syllables (vil-lus), with the stress on "vil". Villus refers to a small, finger-like projection from a mucous membrane, especially the villi lining the small intestine that increase surface area for absorption. In anatomy, it denotes a tiny, hair-like outgrowth that participates in nutrient uptake or in histology describes similar projections on tissues. The term emphasizes microscopic, delicate structures and is used in formal, scientific contexts.

"The enterocyte surfaces are covered with dense villi to maximize nutrient absorption."
"Biopsy revealed elongated villi consistent with a healthy small intestine."
"Researchers studied the villi to understand nutrient transfer in malabsorption disorders."
Pronounce as VIL-us, with the first syllable stressed. IPA: US/UK/AU /ˈvɪləs/. The first vowel is a short as in 'kit,' followed by a clear /l/ and a reduced, unstressed final /əs/. Tip: keep the /l/ light and avoid turning the second syllable into a separate syllable; say it quickly as one syllable after the stressed first. For listening reference, imagine it in 'villus projection' contexts.
Common errors include misplacing stress (e.g., voLus or viLLus), pronouncing the final -us as a full syllable like 'us' in 'bus,' and over-enunciating the second syllable. Correction: place primary stress on the first syllable /ˈvɪləs/, keep the second syllable reduced to /əs/. For the /l/ keep it light and not blended with a following vowel; avoid an intrusive /j/ or extra vowel between syllables.
US/UK/AU share /ˈvɪləs/ but rhoticity matters little here since vowel quality dominates; US and UK vowels are similar in this word. Practitioners may hear a slightly sharper vowel in some UK speech or a less pronounced schwa in rapid US speech. AU tends to be similar to UK, with crisp consonants; overall the rhotic influence is minimal here because there is no rhotic /r/ in this word.
The difficulty lies in maintaining a short, clipped first syllable with a reduced second syllable while keeping an articulate /l/ and avoiding a slurred or overly elided second vowel. The contrast between a brief /ɪ/ and a reduced /əs/ can be tricky in fast scientific talk; practice keeping the second syllable light and quickly merged into the final consonant.
A unique area is the reduction of the second syllable to a schwa plus an /s/ without creating a separate vowel—avoid pronouncing it as 'vil-lus' or 'vil-luhs.' The correct flow is 'VIL-us' with a light, almost invisible second vowel; ensure your tongue posts stay stable as you move from the /l/ to the /ə/ to the /s/.

Villus comes from the Latin villus, meaning a tuft or fringe, diminutive of villus itself from earlier Latin vellus meaning fleece or wool, implying a small hair-like projection. In anatomical usage, the term evokes tiny, hair-like structures that line mucous membranes. The word entered English scientific lexicon in the 18th–19th centuries as anatomy and histology formalized vocabularies for tissue projections. Its plural form villi is the standard in anatomy for multiple projections; a term widely used in physiology, gastroenterology, and embryology. The earliest known uses appear in medieval Latin manuscripts discussing body tissues and later in early anatomy texts when microscopic structures were being described in greater detail. The morphologic sense of villus as a hair-like projection on a mucosal surface strengthened in the 19th century with advances in microscopy, enabling clearer differentiation between villi and other epithelial projections. Modern usage extends to similar projections in other tissues (e.g., placental villi), maintaining the root idea of fine, hair-like extensions that increase surface area or facilitate exchange.
