Pronounce as /ˈtrɛt.ɪ.nɔɪn/. Put the stress on the first syllable: TRET.ih.noyn. The middle syllable is a quick, light /ɪ/ plus /n/. The final is /ɔɪn/, like ‘coin’ with an N. Tip: say 'TRET-ih-noin' in a smooth three-beat flow, ending with a light nasal.”,
Common errors: misplacing stress (saying tre-TI-noin), and mispronouncing the final /ɔɪn/ as /ɔːn/ or /oɪn/. Some speakers insert an extra vowel sound in the middle (tro-tin-oin). Correction: keep primary stress on the first syllable, crisp /ɪ/ in the second, and ensure the final /ɔɪn/ rhymes with coin. Practice slowly: /ˈtrɛt.ɪ.nɔɪn/ and gradually speed up.”,
US/UK/AU share /ˈtrɛt.ɪ.nɔɪn/ with the final /ɔɪn/ closely matching ‘coin.’ Australians may slightly reduce the /ɪ/ in the second syllable to a schwa in rapid speech: /ˈtrətˌnɔɪn/ while still keeping the primary stress on the first syllable. Rhoticity does not alter the core vowels here; vowel quality differences are minor compared to the neutral treatment of /ɪ/ and /ɔɪ/. Overall, maintain the three distinct syllables across accents.”,
Three phonetic features challenge speakers: the two short vowels /ɛ/ and /ɪ/ in the early syllables and the diphthong /ɔɪ/ in the last. The transition from a light /t/ to a vowel can cause a clipped second syllable. The final /ɔɪn/ requires precise tongue positioning to avoid turning it into /ɔːn/ or /ɒn/. Practicing with slow repetitions and listening to medical reading helps solidify the rhythm and final diphthong.”,
Tretinoin carries a three-syllable, stress-bearing sequence with a specific diphthong at the end. The key is the contrast between the brief /ɪ/ in the middle syllable and the long, rising /ɔɪ/ diphthong at the end. Unlike other drug names with silent letters or heavily compounds, tretinoin is phonemically straightforward once you guide the mouth through a steady, three-beat articulation: /ˈtrɛt.ɪ.nɔɪn/.

Tretinoin originated from its chemical structure and class. The root ‘retino-’ traces to retinol (Vitamin A) and related compounds that influence cell differentiation. The suffix ‘-in’ marks a chemical substance, common in pharmaceutical agents. The name likely combines ‘trans-’ or ‘all-trans’ descriptors used to indicate stereochemistry and the retinoid family; historical naming often reflects structural features rather than therapeutic action. First used in the late 1950s to 1960s during the expansion of retinoid research, tretinoin gained medical prominence as a topical acne treatment and later for other dermatologic indications. Over decades, its usage extended to systemic administration in specific dermatologic conditions, with the name persisting as a distinct compound within the retinoid catalog. The pronunciation’s standardization aided global medical communication as prescriptions and product labeling expanded internationally.
