"The brochure references the dorsum surface for the surgical incision."
Pronounce as DOHR-suhm, with primary stress on DOHR. In US and UK, the initial vowel is an open-mid back rounded vowel [ɔː] or close to [ɔ], followed by a rhotic or rhotic-less variant depending on accent. The second syllable uses a schwa or a reduced /ə/ before the final /m/. So: /ˈdɔːr.səm/ (US/UK approximations) and /ˈdɔː.səm/ in non-rhotic accents. Mouth position: start with a wide open jaw for /ɔː/ or /ɔ/, pull the tongue back for the rhotic quality if your dialect requires; end with a relaxed lower lip and a light nasal /m/. Audio reference: you can listen to medical term pronunciations on Pronounce or Forvo for “dorsum.”
Two common mistakes: 1) Reducing the second syllable too strongly to a full vowel like /o/ or /u/; instead use a light /ə/ (schwa) or /əm/. 2) Misplacing the vowel in the first syllable, treating it as a short /ɒ/ or /ɪ/ rather than the longer /ɔː/; aim for the longer, open-mid back vowel. Make sure the /r/ is pronounced with a rhotic quality in rhotic dialects, not omitted in American forms when followed by a syllable with an /r/ element. Practice with a minimal pair: dorsum vs dor-sum (don’t merge to “dorm”).
In US English you’ll hear /ˈdɔːr.səm/ with rhotic /r/ clearly pronounced and the second syllable reduced to /səm/. In UK English, /ˈdɔːs(ə)m/ can be slightly less rhotic depending on region, with a flatter final /m/ and a reduced second syllable. In Australian English, the first vowel tends toward /ɒ/ or /ɔː/ depending on speaker, with a less pronounced rhotic onset and a slightly flatter /ə/ in the second syllable. Across all, the main features are the initial back rounded vowel, a clear primary stress, and a reduced second syllable. IPA references: US /ˈdɔːr.səm/; UK /ˈdɔː.səm/; AU /ˈdɔː.səm/.
Dorsum involves blending a back rounded vowel with a subtle American/UK rhotic or non-rhotic quality and a reduced final syllable. The challenge is maintaining the long back vowel in the first syllable while keeping the second syllable light and not letting it become a full vowel or a nasalized /m/ without voice. Another tricky point is the precise tongue position for /ɔː/ or /ɔ/ and making the /r/ clear if your dialect uses rhoticity. Practice with slow enunciation, then increase speed while preserving the two-syllable rhythm.
No silent letters in dorsum. The word has two syllables with primary stress on the first syllable: DOHR-suhm. The /d/ and /r/ are pronounced together in rhotic accents; the second syllable starts with a light /s/ and ends with a nasal /m/. In careful speech, you’ll articulate the /ɔː/ or /ɔ/ clearly, then reduce the second syllable as /səm/. This pattern shows no stress shift; it consistently carries the main stress on the first syllable in formal contexts.

Dorsum comes from Latin dorsum, meaning back, ridge, or back part of the body. The root dors- means back in Latin, as seen in words like dorsal, dorsally, and indorsed. The transition into English medical lexicon occurred through Latin and early modern scientific German and French texts, where dorsal and dorsum phrases described anatomical surfaces. In early anatomical works, dorsum was used as a precise term to label the posterior aspect of structures such as the tongue (dorsum linguae) or the dorsum manus. Over time, English adopted the term directly as a noun to describe the back surface of a body part in clinical descriptions, surgical notes, and anatomical dictionaries. First known English usage citations appear in 18th- and 19th-century anatomy compendia, where the dorsum was contrasted with the volar or ventral surfaces. The word’s Latin lineage emphasizes a fixed, non-animate noun for anatomical surfaces, which has helped it maintain precise, formal usage across medical and zoological disciplines. In contemporary use, dorsum remains a specialized term, typically found in glossaries, academic papers, and teaching materials rather than colloquial conversation. Its pronunciation, /ˈdɔːr.səm/ in many dialects, reflects the two-syllable structure with primary stress on the first syllable and a mid-to-low vowel in the first syllable, followed by a schwa or reduced vowel in the second.
