3 syllables: Mo, bi, us. Stress on Mo.
MOH-bee-uhs
/ˈmoʊbiəs/
Mobius is pronounced MOH-bee-uhs (/ˈmoʊbiəs/). It has three syllables (Mo-bi-us), with the stress on "Mo". Mobius is a noun referring to a surface with only one side and one boundary, produced by twisting a strip and joining its ends. It is commonly used in mathematics and topology to describe a non-orientable surface. In broader contexts, it also appears in discussions of Möbius strips in science and engineering. The term is often capitalized when referring to the mathematician August Ferdinand Möbius or the Möbius strip concept.

"The Möbius strip has only one surface and one edge, which challenges intuition."
"In topology, a Möbius twist demonstrates how a surface can be non-orientable."
"The engineer's model used a small Möbius strip to illustrate edge-unfolding properties."
In US English, pronounce it as /ˈmoʊ.biəs/ with stress on the first syllable. In UK/Australian accents, it’s /ˈməʊ.bi.əs/ (first syllable stressed, with a rounded /əʊ/ vowel). The second and third syllables use a schwa-like reduction in many casual speech forms. Listen to a native speaker for subtle timing, but keep the two primary syllables明确: MO- bee- uhs. Audio references: consult reputable dictionaries or Pronounce resources.
Common errors: misplacing stress on the second syllable (mo-BI-us) and mispronouncing the US /oʊ/ as a short /o/, or pronouncing the final 'us' as /əs/ rather than /iəs/. Correction: keep stress on the first syllable, ensure /oʊ/ in US or /əʊ/ in UK/AU, and finish with /iəs/ or /əs/ depending on accent; aim for a light, quick /biəs/ ending rather than an overemphasized -us.
US tends to /ˈmoʊ.bi.əs/ with a strong /oʊ/ onset and a distinct /i/ before the final schwa. UK/AU favor /ˈməʊ.bi.əs/ with a rounded /əʊ/ and a slightly shorter first syllable; the final -us often reduced. Rhoticity is optional in non-speech contexts; in careful speech you may hear a clear /ə/ before /s/. Overall, the core is two vowel onsets and a final /əs/ or /iəs/ depending on speaker.
Difficulties stem from the non-intuitive stress pattern for non-native speakers (often misplacing stress), and the diphthong /oʊ/ vs /əʊ/ in US vs UK/AU. The ending can be pronounced as /əs/ or /iəs/ depending on dialect, which can cause confusion with similar-sounding words. The umlaut accent on Möbius also influences vowel quality; learners must tune mouth position to maintain a crisp /oʊ/ or /əʊ/ without over-shortening the middle vowel.
Mobius stress always falls on the first syllable: MO-bi-us. The 'oe' is not separate in English; in the original German, the o with umlaut is pronounced with a close front rounded vowel similar to /ø/ in other contexts, but English rendering uses /oʊ/ (US) or /əʊ/ (UK/AU). Focus on keeping the first syllable prominent and the middle vowel as a clean diphthong, not a long, stressed second syllable.

US: rhotic accent; emphasize the first syllable with a clear /oʊ/ and a distinct /b/ closure. UK/AU: non-rhotic in careful speech; the second syllable uses a shorter /i/ before a soft /ə/; the final /əs/ can reduce to /əs/ or /əz/ in rapid speech. IPA references: US /ˈmoʊ.biəs/, UK/AU /ˈməʊ.bi.əs/. Vowel quality: US diphthong is more open and longer; UK/AU tends toward a rounded /əʊ/ with a shorter nucleus. Consonants: keep the /b/ as a stop with a slight bite; avoid flapping in careful speech; final /s/ should be crisp.
Mobius derives from the surname of August Ferdinand Möbius, a German mathematician who co-discovered and popularized the Möbius strip in 1858. The word Möbius itself enters Western mathematical vocabulary as a proper name used to denote the non-orientable surface he described, later generalized to the fabric of the strip after it is joined to form a loop with a half-twist. The linguistic journey begins with Möbius’ 19th-century publications in German, where the umlaut over the o signals a specific vowel quality and historical German phonology. As the concept spread across European and North American mathematical communities, translators and educators adopted Möbius as a canonical term in topology, retaining the diacritic in many contexts to preserve the proper noun origin. In common usage, the term has become a staple in mathematics, physics, and design, extending to items named after the shape (Möbius strip, Möbius transformation). The word’s first known attestations occur in 19th-century mathematical literature, with broader bilingual adoption following late 19th and early 20th-century scientific communication. The pronunciation in English typically reduces the umlaut to an /iː/ or /i/ vowel in
