Acromion is a bony projection on the scalpular shoulder blade where the clavicle meets the scapula. It forms the highest point of the shoulder and serves as part of the shoulder’s arch, providing attachment for ligaments and muscles. The term is used in anatomy and medical contexts to describe this specific process.
"The acromion forms the boundary of the subacromial space, which is clinically relevant."
"In the anatomy class, she traced the acromion to the clavicle and spine of the scapula."
"Pain at the acromion is often associated with shoulder impingement syndrome."
"The radiologist noted calcification near the acromion on the shoulder X-ray."
Acromion derives from Greek akron, meaning summit or top, combined with omion, from omos meaning shoulder or shoulder region, reflecting its position at the top of the shoulder. The term was adopted into Latin as acromion and later into English anatomical vocabulary. Historically, ancient Greek anatomists described shoulder structures, and as anatomy developed in the 16th–19th centuries, terms like acromion were standardized in medical Latin and then in modern medical English. First known uses appear in early anatomical texts and dissections from the Renaissance period, with consistent usage in the 18th and 19th centuries as anatomy became formalized. The word encapsulates a precise anatomical landmark and has remained stable in medical discourse, with derivatives such as acromial and acromion-related terms in clinical nomenclature.

Pronounce as uh-KROE-mee-on with stress on the second syllable (KROH as in 'crow', mee as in 'me', and on). IPA: US ˌəˈkroʊmiˌɒn or ˌəˈkrəʊmiˌɒn depending on accent; UK ˌækˈroʊmiən; AU ˌaːˈkroːmiən. Place the tip of the tongue near the alveolar ridge for the /k/ and /r/ sequence, then glide into a clear /oʊ/ or /oʊ/ vowel, finishing with an /n/ or /ən/.
Common errors: misplacing stress (say ‘a-CRONE-mee-on’); conflating /ɪ/ with /iː/ in the second syllable; mispronouncing the final /ɒn/ as /ən/ or /ɑn/. Correction: keep secondary stress on syllable 2, use a clear /oʊ/ for the /oʊ/ vowel in ‘acro-’, and finish with a clean /ən/ or /ɒn/ depending on accent. Practice with minimal pairs: acro- /ˈækroʊ/ vs a- /ə-/.
In US you typically hear /ˌæˈkroʊ.miˌɒn/ with r-colored vowels and a slower final /ɒn/; UK tends toward /ˌæˈkrəʊ.miː.ɒn/ with a longer /əʊ/ in the first syllable and a lighter final nasal; Australian often reduces syllable 1 to /əˈkroʊmiən/ with less rhoticity, ending in /ən/. Pay attention to rhoticity, vowel length, and final /n/ realization in each variant.
A key point is the schwa in the first syllable in casual speech, but in careful diction you’ll hear a fuller /æ/ or /ə/ depending on speaker. The second syllable carries the primary /roʊ/ vowel, with a strong, rounded /oʊ/. The final /ɪən/ or /ɒn/ can vary into a syllabic /n/ in rapid speech. Being aware of this variation helps you sound natural in medical contexts.
The combination of a stressed mid syllable, the long /oʊ/ diphthong, and the final nasal can trip learners, especially when trying to maintain a clear /roʊ/ sequence before a nasal. The sequence /kro/ briefly challenges non-native fluent speakers due to rapid consonant clusters. Focus on dividing syllables clearly: a-kro-mi-on, with a crisp /k/ and a controlled /r/.
