/ˈbrɪl.i.ən.si/ in US and UK English. The primary stress falls on the first syllable BRIL, with a light, unstressed -li- before the -an- syllable; the final -cy is pronounced as /si/. For clarity: BRIL – ian – cy, with a quick, clipped second syllable and a final 'see' sound. In practice, say brɪl as in brief with a short i, then -i- as a schwa-like transition to -ən-, and finish with -si pronounced as /si/. Audio examples: Cambridge/Oxford dictionaries or Forvo can provide native-speaker audio for verification.
Two frequent errors: (1) Over-splitting the /ɪ/ in the second syllable, making brill-i-anny instead of the natural brɪl.i.ən.si; (2) Slurring the final /si/ to a z sound or /s/, producing brɪl.i.ən.zai. Correction: keep the final /si/ as a clean /si/ or /siː/ cluster, avoid linking too strongly with the -ən-, and maintain a light schwa-like /ə/ or a reduced /ən/ in the middle. Focus on the primary stress /ˈbrɪl/ and a crisp final /si/.
In US and UK, primary stress on BRIL- with /ˈbrɪl/; the middle vowel is a short /ɪ/ or reduced /ɪ/; final -cy /si/ is clear. US tends toward a slightly stronger r-coloring only if followed by r, but here rhoticity is not relevant. Australian English mirrors UK/US patterns but often features more vowel reduction in unstressed syllables and a slightly broader a in some speakers, though final /si/ remains /si/. Overall, the word remains relatively stable across these variants.
Key challenges include the three-syllable rhythm with a strong initial stress, the mid syllable /ɪ/ followed by a schwa-like /ən/ which can be tricky to connect naturally, and the final /si/ cluster that should be crisp rather than nasalized. The sequence brɪl-i-ən-si requires careful vowel reduction, and many speakers blend /iɪən/ unintentionally. Practice emphasizing the first syllable, then smoothly transitioning through the hiatus to the final /si/.
A distinctive feature is maintaining a clean /si/ at the end without turning it into /zi/ or /siːz/; also ensuring the middle -iən- does not collapse into a single schwa plus -n, but is a light, two-part sound /iən/ with a gentle glide. This word sits between brighter, lighter -li- and the final -ancy/ -ancy variant; keeping the /ɪ/ quality in the first syllable while letting the second syllable relax into /liən/ is key.

US: Rhotic, with crisp /r/ only if influenced by following consonants; keep /ˈbrɪl.i.ən.si/ and let the /i/ in the second syllable be short but not reduced too aggressively.

Brilliancy comes from the Late Latin brilliō (to shine, glitter) + -ancy a suffix forming abstract nouns. The path: Latin brilliāre ‘to shine’ -> Old French brilli(e)rence → Middle English brilliancy, borrowed to describe the quality of shining or dazzling. The word expanded from literal brightness to figurative brilliance: intellectual brightness, wit, or luminous quality in color or light. First attested in English texts around the 16th century, brilliancy gradually accrued a broader semantic range, encompassing not only visible light or color but also metaphorical shine, such as intellectual brilliance or performance that stands out for its clarity, boldness, or ingenuity. Over time, spelling variants stabilized into the modern ‘brilliancy,’ though ‘brilliancy’ remains a classic but less frequent form than ‘brilliance.’
