Say STIM-ya-lus with the primary stress on STIM. IPA: US/UK/AU /ˈstɪm.jə.ləs/. The middle vowel is a short /ɪ/ in STIM, the second syllable uses a schwa /ə/ or a reduced vowel, and the final is /ləs/ with a light /l/ followed by /əs/. Tip: keep the /j/ glide between the second and third syllables, producing /ˈstɪm.jə.ləs/ rather than /ˈstɪ.mə.ləs/.
Common errors: 1) Slurring the middle /j/ making it /ˈstɪm.ləs/ or /ˈstɪm.jləs/. 2) Over-suppressing the /j/ and merging /jə/ into /ə/ or /ju/; 3) Misplacing stress to second syllable. Correction: articulate /ˈstɪm/ first syllable clearly, insert a light /j/ as a separate glide to form /jə/, and keep the final /ləs/ stable. Practicing with minimal pairs can help: stimulus vs. stimulus-incorrect blends.
In all three accents, initial /ˈstɪm/ remains stable. UK and US share /ˈstɪ.mjuː.ləs/ or /ˈstɪm.jə.ləs/; Australian tends to reduce the second syllable slightly more, with /ˈstɪm.jə.ləs/ or /ˈstɪm.mjʊ.ləs/? but primarily /ˈstɪm.jə.ləs/. The main differences lie in vowel quality in the unstressed syllables and the presence of a rhotic /r/ in some American dialects depending on the speaker. Practice focusing on /ˈstɪm.jə.ləs/ for all three, but be mindful of subtle vowel shifts in fast speech.
The difficulty lies in the three-syllable structure with a mid stress and a weak, reduced final syllable. The /j/ is a semi-vowel glide that can be easy to skip, and the middle /ə/ can reduce to a schwa or disappear in rapid speech. Additionally, listeners may expect a different consonant cluster between the middle and final syllables. Focus on maintaining the /j/ glide and a crisp final /ləs/ to avoid truncation.
There are no silent letters in Stimulus. All three syllables carry pronunciation: /ˈstɪm.jə.ləs/. The /j/ in the second syllable is pronounced as a consonant glide between the /m/ and the /ə/ vowel, so you should hear a smooth transition rather than a silent or dropped letter.

Stimulus comes from the Latin stimulare, meaning to spur or to goad, from stimulus ‘a goad, spur.’ The noun form emerged in English in the 17th century, initially in philosophical and scientific discourse to describe something that incites action. The root stimu- is connected to stir, prick, or incite, shared with stimulus in many Romance languages where similar terms exist (e.g., stimulare in Latin, estimular in Spanish). Over time, the concept broadened beyond physical pricks or spurs to refer to any external factor that provokes a response, notably in psychology, biology, economics, and media studies. The plural form stimuli is commonly used in scientific writing, with singular stimulus used in everyday language and some specialized domains. The pronunciation preservation of the |-tjuːs| ending aligns with older Latin-derived spellings, while modern usage often aligns with the phonetic ending /-əs/ or /-əs/ depending on accent. First known uses surface in medical and physiological texts discussing sensory input and reflex arcs, evolving to include abstract, social, and economic triggers in contemporary discourse.
