3 syllables: hy, a, loid. Stress on hy.
HEYE-uh-loyd
/ˈhaɪ.ə.lɔɪd/
hyaloid is pronounced HEYE-uh-loyd (/ˈhaɪ.ə.lɔɪd/). It has three syllables (hy-a-loid), with the stress on "hy". Hyaloid refers to a transparent, glassy structure or membrane, often describing the hyaloid body in the eye or a hyaloid canal. It denotes clarity and translucence, typically used in anatomical contexts. The term originates from Greek roots and is used in scientific discourse to specify a hyaloid layer or vessel, especially in ophthalmology and embryology.

"The hyaloid membrane surrounds the developing lens during fetal eye formation."
"Researchers studied the hyaloid artery to understand retinal vasculature development."
"Histology identified a hyaloid canal within the vitreous body."
Break it as hi-AL-oid with stress on the second syllable: /ˈhaɪ.ə.lɔɪd/. The first syllable sounds like 'high', the middle is a schwa-like 'uh', and the final 'oid' rhymes with 'void'. Mouth: start with a high front vowel, glide into a mid-central vowel, then close with a long 'oy' diphthong. You’ll hear the two-part rhythm: HI-uh-LOyd with a clear pause before the final 'loid' in slow speech.
Two frequent errors: 1) compressing the word to HY-LOID (skipping the mid vowel). 2) misplacing the primary stress on the first syllable (HY-a-LOID). Correction: keep a distinct middle vowel /ə/ or /ə/ and place primary stress on the second syllable: /ˈhaɪ.ə.lɔɪd/. Practice by saying three-syllable rhythm: hi-uh-LOID, with the second syllable slightly louder.
In US and UK, the middle vowel tends toward a reduced /ə/ and the final diphthong remains /ɔɪ/. US tends to be rhotic with a slightly tensed final /ɔɪd/; UK often features closer vowels in the middle and crisper /ɔɪ/. Australian tends to a more centralized /ə/ and a slightly broader /ɔɪ/ diphthong. Overall, the core segments /ˈhaɪ.ə.lɔɪd/ stay intact, but the mid-vowel quality and vowel length shift subtly by accent.
Because it combines a strong initial stress with a mid syllable /ə/ that can be quickly reduced in rapid speech, and a trailing /lɔɪd/ diphthong that isn’t common in all languages. The contrast between /haɪ/ and /ə/ followed by the rounded /lɔɪd/ demands precise tongue positioning and lip rounding. Focus on keeping the /ɪ/ or /ɪə/ transitioning smoothly into /ə/ before the /lɔɪd/.
Mind the pause-like separation between the first two syllables and the final /ɔɪd/: hi-uh-LOID. Keep the second syllable short but full, avoiding blending into HY-ALOID. Practice with a slow pace, then gradually increase speed while maintaining distinct /ə/ in the middle and a clean /ɔɪd/ at the end.

Hyaloid comes from the Greek hyalos (glass, transparent) combined with the Latin-derived suffix -oid, meaning ‘resembling’ or ‘like.’ The root hyalos appears in ancient Greek anatomy and philosophy to describe something glassy or transparent. The term entered scientific vocabulary in the 19th century as microscopy and histology advanced, allowing precise description of ocular structures. Early usage framed the hyaloid to denote a vitreous body or membrane; as embryology and ocular pathology evolved, hyaloid appeared in contexts such as the hyaloid artery and canal, which are critical for lens development and retinal formation. The word’s semantic core—glass-like translucence—remains consistent, though applications broadened to other hyaloid-like tissues in comparative anatomy. First known uses appear in medical texts of the late 1800s, with gradual standardization in ophthalmology literature by the early 20th century.
