uhl-truh-VEYE-uh-lit
/ˌʌltɹəˈvaɪəlɪt/
ultraviolet is pronounced uhl-truh-VEYE-uh-lit (/ˌʌltɹəˈvaɪəlɪt/). Ultraviolet refers to electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays. It encompasses UV-A, UV-B, and UV-C bands. The term combines ultra- (beyond) with violet, highlighting its position just beyond the violet end of the visible spectrum. It’s commonly used in contexts like tanning, sterilization, and material fluorescence.

You say ul-tra-vi-o-let with primary stress on the -vi- syllable: /ˌʌl.trəˈvaɪ.ə.lət/ (US) or /ˌʌl.trəˈvaɪ.ə.lət/ (UK). Start with a light schwa in the first syllable, then a clear -trə-, then a strong stress on -vaɪ-, followed by -ə-lət. Mouth positions: lips relaxed for /ɚ/ in the second syllable, tongue rising to /aɪ/ in -vi-; end with a neutral /lət/. An audible, even tempo helps the rhythm. Audio references: Cambridge or Oxford dictionaries provide audio; you’ll hear the natural emphasis on -vaɪ-.
Common errors: (1) Misplacing stress on -vio- or spreading stress too evenly; ensure primary stress on the 'vaɪ' syllable. (2) Slurring /ˈlaɪ/ into /lət/—don’t merge -li- and -ot-; keep -vaɪ- distinct. (3) Dropping the /ə/ vowels in the middle; pronounce the two schwas lightly but present. To correct: practice as a sequence ul-trə-VAɪ-ə-lət, exaggerate syllable separation slowly, then normalize tempo. Use slow, measured practice with IPA cues: /ˌʌl.trəˈvaɪ.ə.lət/.
Across accents, the main difference is vowel quality in the /aɪ/ diphthong and the rhoticity. US often retains a rhotic /r/ in surrounding syllables? Actually ultraviolet is non-rhotic in most British varieties; US tends to an rhotic approximant in linked phrases if the 'r' is present elsewhere in the phrase. The /ə/ vowels remain schwa or reduced in faster speech. Australian tends to a clear /ɐ/ or /ə/ in some contexts; stress remains on -vaɪ-, but vowel clarity can shift slightly toward a more centralized /ə/ in slower speech. IPA: US/UK/AU: /ˌʌl.trəˈvaɪ.ə.lət/.
The difficulty lies in the long -vi- diphthong /aɪ/ followed by a light, unstressed -ə- and then -lət, which demands precise timing and syllable separation. Learners often misplace the primary stress on -vaɪ-, or blend /ə/ vowels, causing a less natural rhythm. Additionally, the sequence -trə- before the diphthong requires a quick, controlled transition. Practicing with slow, exact IPA cues helps solidify the natural flow.
No. All letters in ultraviolet are pronounced in standard English pronunciation. The syllables ul-tra-vi-o-let are spoken with staccato clarity: /ˌʌl.trəˈvaɪ.ə.lət/. The potential confusion comes from the neutralized /ə/ vowels and the unstressed ending -lət, but each letter corresponds to an audible sound. Mouth positions: start with light /ʌ/, advance to /trə/ cluster, then /ˈvaɪ/ diphthong, then /ə.lət/.

Ultraviolet is a compound of ultra- (beyond, extreme) from Latin ultra, meaning 'on the far side of' or 'beyond', and violet, from Latin violaceus, from violer, related to the violet color. The term was coined in the 19th century as scientific understanding of the electromagnetic spectrum expanded. Ultraviolet radiation exists just beyond the visible violet end of the spectrum, with wavelengths roughly 10 nm to 400 nm. The prefix ultra- was used in scientific terms in the 17th–19th centuries, and violet as a color word traces to Middle English from Old French violet, from Latin violaceus, akin to viola 'blue' in certain Romance languages. First known use of the exact term ultraviolet in English dates to the 1850s in the context of Faraday’s and subsequent scientists’ explorations of light beyond visible range, formalizing its detection and study with spectroscopy and the discovery of UV effects on materials and organisms.
