Pronounce as di- DYOOS, with the primary stress on the second syllable: /dɪˈdjuːs/. The first syllable is a short /dɪ/ and the second features a /dʒ/ quality emerging from the /d/ and /juː/ sequence, giving a /djuː/ sound before the final /s/. Keep the lips rounded lightly for the /juː/ and finish with a crisp /s/. Audio references: you can compare to words like reduce (re-DYOOS).
Two common errors are misplacing the stress or mispronouncing the /djuː/ sequence. Some speakers might say /ˈdjuːdʒəs/ or /ˌdɪˈduːs/ by flattening the /dʒ/ into a simple /j/ or misplacing stress. Correction: ensure the /d/ of the second syllable attaches to a long /juː/ with the /d/ released as /d/ then glide to /juː/ (so /dɪˈdjuːs/). Keep the second syllable stressed and the final /s/ crisp. Practice by saying di + juː + s in a smooth glide.
Across US/UK/AU, the main variation is vowel quality in the /juː/ part and the rhoticity of the surrounding vowels. US speakers may have a slightly shorter /juː/ with a less rounded preceding vowel; UK tends to a clearer /ˈdɪ.djuːs/ with a more pronounced /dʒ/ blending into /juː/; AU often resembles UK, keeping /ˈdɪˌdjuːs/ but with a flatter overall vowel. Stress remains on the second syllable across all. IPA references: US /dɪˈdjuːs/, UK /dɪˈdjuːs/, AU /dɪˈdjuːs/.
The difficulty lies in the /djuː/ cluster: the 'd' blends into the 'j' sound, creating a /dʒ/ edge that some learners mispronounce as /duːz/ or /djuːz/ without the proper abrupt release from /d/. Also, the secondary stress potential in connected speech can blur the /ɪ/ in the first syllable. Focus on a clean /d/ release into the /juː/ glide, and then a crisp final /s/ to avoid a trailing vowel sound.
In Deduce, the primary stress is on the second syllable (de-DUCE), so you emphasize the /duː/ portion while maintaining a lighter first syllable. The /d/ at the start of the second syllable is not aspirated as strongly as in word-initial positions, but you still articulate a clear /d/ leading into the /juː/ glide and then the final /s/. IPA: /dɪˈdjuːs/. Keywords: stress placement, /d/ release, /juː/ glide.

Deduce comes from the Latin word deducere, meaning to lead down or bring down, from de- (down) + ducere (to lead). The sense evolved through Old French and later Middle English, where the concept of deriving a conclusion from premises emerged in scholastic and philosophical discourse. The key semantic shift centers on the cognitive act of drawing a line from observed facts to a consequence. By the 17th century, deduce had solidified as a formal verb in English for logical inference. Early uses align with formal reasoning, probing how one can derive conclusions through rational steps. The root ducere repeatedly appears in words relating to leading or drawing (induce, reduce, conduct). Over time, deduce narrowed to the specific act of logical derivation rather than any general inference, distinguishing it from more tentative forms like guess or suppose. First known printed instances appear in scholarly prose of the Renaissance and early modern period, with gradual integration into everyday language as analytic reasoning became common in education and scientific writing.
