3 syllables: Chem, is, try. Stress on Chem.
KEM-uh-stree
/ˈkɛməstɹi/
Chemistry is pronounced KEM-uh-stree (/ˈkɛməstɹi/). It has three syllables (Chem-is-try), with the stress on "Chem". Chemistry is the science that studies matter—its composition, properties, and the changes it undergoes. The term also refers to the field of chemical reactions and interactions, often taught in schools and universities. In common use, it can describe the relationship between people or the atmosphere in a specific situation, as in “there's chemistry between them.”.

How to Pronounce Chemistry
"Her chemistry class covers atoms, molecules, and reactions."
"The two scientists had great chemistry in the lab, quickly pairing on experiments."
"People sensed chemistry between the presenters, making the conference engaging."
Phonetically, Chemistry is /ˈkɛm.ɪ.stri/ in US and UK; Australia follows the same three-syllable pattern. The main stress is on the first syllable CHE-, with a short E in the second syllable and a clear ‘str’ blend in the third. Mouth position: start with a mid-front vowel /ɛ/ as in “bed,” then a short /ɪ/ for the second syllable, and an unstressed /i/ in the final syllable. Practice with slow enunciated breaks: CHE-mi-try, then smooth to CHEM-uh-try in connected speech.
Common errors include pronouncing the first vowel too long or tense (e.g., /ˈtʃɛm.ɪː.stri/) and mispronouncing the final -stry cluster as /-stri/ with a strong /r/ or /ɹ/. Another frequent pitfall is collapsing the second syllable into a quick schwa, giving CHEM-stri. Correct approach: keep /ɛ/ in the first syllable, then a short /ɪ/ before the /str/ cluster, and finally a light /i/ in the last syllable. Practice with minimal pairs to stabilize the /ɪ/ and /i/ contrast: CHE-mi-stry vs CHE-me-st ry.
In US, UK, and AU, the pronunciation centers on /ˈkɛm.ɪ.stri/. Rhoticity affects only the linking to surrounding sounds, not the core syllables; rhotic speakers won’t add an extra rhotic vowel here, but American pronunciation is often a bit more clipped. UK and AU maintain the same /ˈkʰɛm.ɪ.stri/ with a similar schwa handling in connected speech. The main differences arise in vowel quality and the strength of t-voicing before the final -stry: US may be slightly flatter, UK sometimes slightly rounded in the second vowel, and AU often a tad broader in the first vowel. IPA references align closely across dialects for this word.
The challenge lies in the smooth sequence of three syllables with a fast transition from /ɛm/ to /ɪ/ and the cluster /str/ in the final syllable. The unstressed second vowel /ɪ/ can be reduced toward a schwa in casual speech, which can blur the word’s rhythm. Additionally, non-native speakers often hesitate with the /t/ in American pronunciation or mispronounce the /str/ blend as /s-tr/ or /st/ separately. Focus on maintaining a clean /m/ + /ɪ/ + /str/ transition and keep final /i/ short and light.
Chemistry features a three-syllable structure with a consonant cluster /str/ in the final syllable, and a primary stress on the first syllable. The middle vowel is a short /ɪ/ rather than a long or stressed vowel, which many learners mispronounce as /ɑ/ or /iː/. The final /i/ is typically a short, barely discernible vowel in fluent speech. Mastery comes from practicing the /ˈkɛm/ onset, the /ɪ/ nucleus, and the /str/ coda together, then integrating them into natural, connected speech.

Chemistry derives from the Middle French chimie, borrowed from Latin medicina chymica, which itself arose from the Greek word khemeia (χημεία). The Greek khemeia referred to the art of alloying metals and transmuting substances, evolving into the broader sense of chemistry as the science of substances and their transformations. In medieval and early modern Europe, the term encompassed what we’d now call alchemy and early chemistry, including attempts to transmute base metals into noble metals and to discover the elixir of life. By the 17th century, as experimental methods and controlled laboratory practices matured, the modern discipline of chemistry emerged, distinguishing itself from alchemy through systematic observation, reproducibility, and theoretical grounding in atomic theory. The word entered English usage in the 16th century, with scientific writers gradually adopting chemistry to denote the study of substances, their structures, reactions, and properties. Over time, chemistry split into branches such as organic, inorganic, physical, analytical, and biochemistry, but the core idea—a rigorous investigation of matter and its changes—remains central to all its subfields.
