US: rhotic A-R sound on the R-less US regions? No; amniotic does not have R here. Focus on U.S. /oʊ/ in third syllable if your speaker uses /oʊ/ rather than /ɔɪ/. UK: watch for non-rhotic; /ɒɪ/ diphthong closer to /ɒɪ/ with less lip rounding. AU: more open /ɔɪ/ with slightly broader vowel. Vowel shifts: /æ/ as in cat; /ɪ/ in the middle; /ɔɪ/ or /əɪ/ glide; keep the tongue back slightly for /ɒɪ/ vs /ɔɪ/. IPA references: US /ˌæm.niˈoʊ.ɪ.tɪk/; UK /ˌæm.niˈɒɪ.tɪk/; AU /ˌæm.niˈɔɪ.tɪk/.
"The amniotic fluid level was measured during the prenatal ultrasound."

Amniotic comes from the amnion, a term dating from the Greek amnion meaning ‘the fetal membrane’ and the suffix -ic, meaning ‘pertaining to’. The amnion itself derives from the Greek amnion, a term used in ancient medical texts to describe the innermost protective layer enclosing the embryo. The word entered English medical vocabulary through Latinized Greek usage in anatomy texts in the 17th-18th centuries as medical science began to systematically describe fetal membranes and allantoic and amniotic structures. Over time, amniotic expanded in obstetrics to refer to the amniotic sac and its fluids, as well as physiological or pathological conditions related to the amnion. First known uses appear in early modern anatomical writings and textbooks that codified fetal membranes, with later specialization in obstetric and gynecological literature as ultrasound and obstetric pathology developed in the 20th century.

Break it as am-NI-ot-ic. Primary stress is on the second syllable: /ˌæm.niˈɒɪ.tɪk/ in UK and US broad pronunciations, while US often transcribes as /ˌæm.niˈoʊ.ɪtɪk/ and Australians as /ˌæm.niˈoːɪ.tɪk/. The first syllable is /æ/ as in cat, the second /nɪ/ as in near, the third /oɪ/ or /ɒɪ/ depending on accent, and the final /k/ as in kit. Keep the mouth relaxed on the first syllable, then tighten a little for the stressed second: am-NI-ot-ic with a clear /ɒ/ or /oʊ/ diphthong in the third.
Common errors: shying away from the mid vowel in /æ/ leading to /æmniɒɪtɪk/ vs intended /ˌæm.niˈɒɪ.tɪk/. Another misstep is misplacing the stress, pronouncing am-NI-ot-ic with stress on the first or third syllable. Finally, some say /æmˈniː.ɔːtɪk/ or merge /oi/ into /iː/; practice the /ɒɪ/ or /oɪ/ diphthong in the third syllable. Correct by practicing the sequence am - NI - ot - ic with a crisp second-syllable peak and an accurate /ɒɪ/ or /ɔɪ/ glide before the final /tɪk/.
US typically /ˌæm.niˈoʊ.ɪ.tɪk/ with rhotic speech and a clear /oʊ/ in the third syllable; UK often uses /ˌæm.niˈɒɪ.tɪk/ with a less pronounced rhotic and a broader /ɒɪ/; Australian tends toward /ˌæm.niˈɔɪ.tɪk/ or /ˌæm.niˈɒɪ.tɪk/, with a vowel closer to /ɔɪ/ and less elongated /oʊ/ in many speakers. The key is the diphthong in the third syllable and the rhoticity or lack thereof affecting vowel quality.
Difficulties stem from the tri-syllable rhythm, the central /ni/ clusters, and the third syllable’s diphthong that varies across accents. The stress on NI can feel counterintuitive if your native language places stress elsewhere. Additionally, the /ɒɪ/ or /ɔɪ/ glide in the third syllable challenges speakers not used to diphthongs with back vowels. Slow, precise articulation of each segment and listening practice with native speech helps overcome these challenges.
There are no silent letters in amniotic. Every letter contributes to phonemes: the initial /æ/ or /æm/, the /n/, the stressed /niˈɔɪ/ or /niˈɔɪ/ sequence, and the final /tɪk/. The interesting feature is the diphthong in the third syllable, which changes slightly by accent. You’ll hear the most natural pronunciation when you maintain a steady rhythm and keep the second syllable clearly stressed.
