hemodynamic

Break it into four syllables: he-mo-dy-na-mic. Primary stress falls on the third syllable: heh-muh- DYE-nuh-mik with the stress on 'dy' (ˈdaɪ). IPA: US ˌhɛ.moʊ.dɪˈnæ.mɪk, UK ˌhɛˈməʊ.dɪˈnæ.mɪk, AU ˌhɛˈmə.dɪˈnæ.mɪk. Start with a clear 'he' as in heh, 'mo' as in mo, 'dy' rhymes with 'die', then 'na' and 'mic' with schwa-like vowels.

Two frequent issues: misplacing stress and vowel quality in the middle syllables. People often flatten the sequence to four equal syllables and misplace the primary stress on the second or fourth syllable. Ensure the main emphasis is on the 'dy' syllable: he-mo-DY-na-mic. Also watch final -mic: avoid pronouncing it as 'mick' or 'mık'; keep a light schwa in the 'na' and a clear consonant at the end.

US tends to have a rhotic, clearer 'r' and a slightly longer 'dy' diphthong; UK may reduce some vowel contrasts and keep non-rhoticity depending on region, with a slightly shorter 'o' in 'he-mo-'; AU shares rhotic tendencies in many speakers but often features flatter vowels and a more clipped final -mic. IPA landmarks: US ˌhɛ.moʊ.dɪˈnæ.mɪk, UK ˌhɛ.məˈdʌɪ.nə.mɪk, AU ˌhɛ.məˈdɪ.næ.mɪk.

It combines multiple stress shifts and several vowel qualities in a short span: the 'e' in 'he' is a reduced vowel in rapid speech, 'mo' often reduces, 'dy' demands a clear diphthong to avoid blending with 'na', and the final '-mic' requires a crisp stop with a soft 'm' onset. The sequence also crosses syllables quickly, challenging non-native speakers to keep the four-syllable rhythm intact while placing primary stress on the third syllable.

A key is distinguishing the 'dy' as a strong office-like 'dye' sound, not a simple 'd' or 'di' as in some lighter terms; practice linking the 'dy' with the following 'na' so the transition is seamless. The 'ic' ending should be a light, unstressed -ɪk, not a heavy 'ick'.
