/prəænθoʊsaɪˈænɪdɪnz/
Proanthocyanidins is pronounced pruh-an-thoh-seye-AN-id-inz (/prəænθoʊsaɪˈænɪdɪnz/). It has seven syllables (Pro-an-tho-cy-an-i-dins), with the stress on "cy". Proanthocyanidins are a class of polyphenolic compounds found in plants, particularly seeds and bark, that contribute to astringency and antioxidant activity. They are oligomeric flavonoids formed by condensation of catechin and epicatechin units. In research, they’re noted for potential health effects and are often discussed in the context of wine, grapes, and various fruits.

- You miss the /θ/ dental fricative by substituting /t/ or /d/, producing pro-AN-tho-sai-A-ni-dinz instead of pro-AN-tho-SAI-a-ni-dinz. To fix, practice isolating /θ/ with tongue tip between upper and lower teeth and a light breathy release. - Misplacing stress across syllables: avoid misplacing primary stress on -tho or -sai. Use slower, deliberate pronunciations and mark the syllable boundaries when practicing. - Over-emphasizing the long vowel in -sai- (ai) or conflating it with /eɪ/. Target /aɪ/ as the glide between /s/ and /ɪ/ in the next syllable. - Final cluster /dɪnz/ often becomes /dənz/ or /dɪnz/ with a reduced schwa. Practice crisp alveolar /d/ and a clear /z/.
"Proanthocyanidins have been studied for their potential role in supporting cardiovascular health."
"The astringent taste of red wines is largely due to proanthocyanidins."
"Researchers isolated proanthocyanidins from grape seeds to evaluate their antioxidant properties."
Break it as pro-an-tho-cya-ni-dins. Phonetic: US /ˌproʊ.ænˌθoʊˌsaiˈæn.ɪ.dɪnz/. Primary stress on the -cy (sai) syllable? Note: there’s some variation, but you’ll hear stress around the ‘cy’ portion in academic speech. Start with /proʊ/ as in 'pro', then /ˈæn/ or /ˌæn/ for the 'an' cluster, /θoʊ/ for the 'tho' with a dental fricative /θ/, then /ˈsai/ (sai) as in 'sigh', then /ˈæn/ for 'an', /ɪ/ as a short i, and /dɪnz/ ending with /nz/. Audio references: see Pronounce or Forvo listings for proanthocyanidins.
Mistakes: misplacing the dental fricative /θ/ (pronouncing as t or d), mis-sequencing the syllables causing a jarring /ˈθoʊ/ vs /ˈθən/ segment, and mis-stressing the long vowels in -sai- and -nidins. Correction: practice the sequence pro-_an-tho-sig-AN-i-dins? Not quite. Say pro-AN-tho-SAI-a-ni-dins with clear /θ/ in the third segment, keep /sai/ as one syllable with a long 'i', and maintain final /dɪnz/ with a soft 'd' and clear /z/ nasal. Use slow repetition and a tongue-tap for /θ/.
In US, you’ll hear /ˌproʊ.ænˌθoʊˌsaiˈæn.ɪ.dɪnz/ with relatively flatter vowels in unstressed syllables and rhotics affecting surrounding vowels. UK/AU reduce rhotics, so /ˌprəʊ.ænˌθəʊˌsaiˈæn.ɪ.dɪnz/ with non-rhotic r-less vowels. The main contrast is vowel quality: US uses /oʊ/ vs UK/AU /əʊ/ in some positions, and /ɪ/ vs /ɪ/ in the final syllables. Also the /θ/ articulation remains consistent, but preceding vowels may be slightly more closed in US and more open in UK/AU.
This word mixes a long initial sequence of syllables with dental fricatives and multiple vowels in a row: pro-AN-tho-SAI-a-ni-dins. The cluster -th- followed by -o- and a high front vowel in -sai- creates a challenging transition for non-native speakers. The dental /θ/ is less common in many languages, and the sequence stress pattern shifts across syllables, making it easy to misplace emphasis. Practice slowly, then gradually speed up while keeping a clean /θ/ and a steady /ai/ diphthong.
Does 'Proanthocyanidins' have a stress pattern that moves between syllables depending on media or speaker? Yes. In technical pronunciation, you may hear secondary stress on -an- or -tho- depending on the discourse emphasis, but the most stable approach places primary focus around the 'sai' vowel cluster and the ending '-idins' to ensure the final nasal consonants are clear. IPA guidance helps: /ˌproʊ.ænˌθoʊˌsaiˈæn.ɪ.dɪnz/—keep final /nz/ crisp and avoid de-vocalizing the last syllable.

- US: rhotic vowels are pronounced with an /r/ in nearby segments; in this word, /proʊ/ is typical, and /θoʊ/ features rounded mid vowels. - UK: non-rhotic; /prəʊ/ and /θəʊ/ with slightly less rhoticity; final /ɪ.dɪnz/ retains clarity but with sharper syllable timing. - AU: often similar to UK but with subtle Australian vowel raising in /əʊ/ and broader diphthongs; ensure /θ/ is clearly enunciated. For all, keep /θ/ crisp, avoid substituting /f/ or /t/. IPA references: US /ˌproʊ.ænˌθoʊˌsaiˈæn.ɪ.dɪnz/, UK /ˌprəʊ.ænˌθəʊˌsaiˈæn.ɪ.dɪnz/, AU /ˌprəʊ.ænˌθoʊˌsaiˈæn.ɪ.dɪnz/.
Proanthocyanidins derives from two parts: ‘pro’ (before) and ‘anthocyanidin’ (the aglycone pigments that give flowers and berries their red, purple, or blue colors). The term first points to their role as precursors or polymeric forms related to anthocyanidins. The suffix -ins marks a chemical class, common in natural products naming. The word anthocyanidin itself comes from Greek anthos (flower) + kyanos (blue), referring to the blue/purple hue of some pigments. In the 20th century, chemists recognized these condensed tannins as oligomeric polymers of flavan-3-ol units (such as catechin and epicatechin). Early research labeled them condensed tannins, distinguishing from hydrolyzable tannins. The current preferred term proanthocyanidins emphasizes their polymeric nature and relationship to anthocyanidins, with first usage appearing in mid-20th century pharmacognosy and food chemistry literature as scientists mapped polyphenol substructures in plants.
