Assume is pronounced uh-SOOM (/əˈsum/). It has two syllables (As-sume), with the stress on "sume". Assume is a verb meaning to take on, accept, or suppose something as true without full proof. It also means to take excessive or unwarranted power or responsibility. In everyday use, people often assume facts not in evidence or assume roles without consent, so precise pronunciation helps avoid miscommunication in nuanced contexts.

"Don’t assume the outcome; gather more data first."
Pronounce it as a-SUME, with secondary stress on the second syllable. IPA US/UK/AU: /əˈsjuːm/. Start with a relaxed, unstressed schwa in the first syllable, then a clear /s/ + /j/ glide to /uː/ followed by /m/. Ensure the /juː/ is a true yod + long U sound rather than a flat “oo.” Finish with a light bilabial nasal /m/. Audio reference: you can hear it in standard dictionaries or pronunciation videos; try Cambridge or Oxford entries for an audible model.
Common mistakes: (1) Stress on the first syllable a-SUME vs. a-SUME? Noticing the right primary stress on the second syllable is critical; many learners place the stress on the first syllable, sounding like ‘ASS-ume.’ (2) Flattening /juː/ into /uː/ as in “soon” or “boom,” which eliminates the yod glide. (3) Dropping the final /m/ or making it a syllabic /n/. Correction: keep a short, crisp /m/ at the end and allow the /j/ to blend into /uː/. Practice with minimal pairs: expose 'assume' vs 'resume' to hear the difference in vowel quality and syllable stress.
In US English you’ll hear /əˈsuːm/ with a slightly rhotacized or non- rhotic effect depending on speaker, but the /r/ does not alternate in this word. UK English tends toward /əˈsjuːm/ with a pure yod glide /j/ in /sjuː/. Australian English is similar to UK, but listeners may notice a more centralized first syllable vowel and a slightly quicker pace; the second syllable is the strong, long /uː/ with final /m/. All share the /ˈsuːm/ nucleus but differ in the onset and the pronunciation of /j/ and the initial schwa.
The difficulty comes from the two-part rhythm: unstressed schwa + stressed /ˈsuːm/ with the /j/ glide blending into the long /uː/. Learners also often misplace the stress, pronouncing it a-SUME or a-suum with poor quality of /uː/. The contrast with 'resume' (re-SUME) and 'assume' (a-SUME) hinges on the vowel quality and syllable structure. Finally, rapid speech reduces the clear /j/ and the glide into a short, fast /suːm/, which can blur the pronunciation. Practice the precise glide with careful mouth positions.
There is no silent letter in assume, but there is a predictable stress pattern: secondary stress is not present; primary stress lands on the second syllable. The /j/ is not silent; it forms a /sjuː/ onset. The common pitfall is misplacing the stress on the first syllable or reducing /juː/ to /uː/ or /juːm/ with a weaker glide. Keeping the /j/ intact helps maintain a precise /sjuː/ cluster and a clean final /m/.

Assume comes from the Latin assumere, formed from ad- (toward) + sumere (to take, take up; from sub- ‘up’ + sumere ‘take’). The Latin root sumere itself derives from the proto-Italic *sub- and *-emere, connected to taking or taking up. In Latin, assumere carried meanings of taking upon oneself or taking on. The word entered English via Old French as assumer and early modern English as assume, retaining the sense of taking on responsibilities or positions, and later, the sense of taking for granted or presuming. The term broadened to include mental acts of supposing something to be true without proof. Over centuries, “assume” has maintained a strong association with taking upon oneself duties or appearances and with presuming or supposing, distinguishing it from more cautious verbs like “doubt” or “verify.” The semantic evolution reflects shifts in how speakers encode stance toward information—moving from external action (to take up) toward internal belief or conjecture (to presume). The earliest English attestations date from the 14th–15th centuries, aligned with the Latin and French pathways that shaped many academic and legal uses of the term. Today, “assume” spans practical, social, and formal contexts, from assuming a role to assuming a stance or hypothesis.
