/ɝlənˈmaɪɚ flæsk/
Erlenmeyer Flask is pronounced ur-luhn-MEYE-ur-flask (/ɝlənˈmaɪɚ flæsk/). It has four syllables (Er-len-mey-er Flask), with the stress on "mey". Erlenmeyer Flask is a lab glassware item with a conical body and a narrow neck, used for mixing chemicals and heating solutions. It combines a wide base for stability with a slender neck to reduce splashing. The term denotes both the inventor’s surname (Erlenmeyer) and the vessel (Flask).

- Pronounce Erlenmeyer as a single, flat syllable; break it into ER-lən-MY-er for clarity. - Merge the 'meyer' into one quick beat, losing the /maɪər/ diphthongal sequence; practice as /maɪər/ (my-er) rather than /maɪɚ/. - Slur the boundary with Flask; maintain a crisp boundary: Erlenmeyer (ER-lən-MY-er) + Flask. - Weak final /æ/ in Flask; keep the short open front vowel distinct from /æ/ in other words. - Flap/tap /r/ in American speech within Erlenmeyer when rapid speech occurs; ensure you still produce the rhotic sound clearly. For corrections, slow the sequence to three syllables (ER-lən-MY-er), exaggerate the second syllable’s stress, then gradually compress while maintaining accuracy.
How to Pronounce Erlenmeyer Flask
"In the chemistry lab, she swirled the Erlenmeyer flask to mix the reacting solutions."
"The instructor handed out Erlenmeyer flasks for the titration experiment."
"Please cover the Erlenmeyer flask to prevent evaporation during heating."
Pronounce it as ER-lən-MY-er FLASK. In IPA US: ˈɜːrlənˌmaɪər flæsk; UK: ˈɜːlənˌmaɪə flæs(k); AU follows US on the Erlenmeyer part: /ˈɜːlənˌmaɪə/ with the final /ə/ less prominent. Primary stress on ERL- part; second stress on -MAI- in MYER. Mouth positions: start with a mid-back r-colored vowel /ɜː/ drawn from “bird” without rhotic r release; then a schwa or /ə/ in the second syllable, then /ˈmaɪər/ for “meyer” with a long I and mid rhotic glide; finish with a hard /flæsk/ for “flask.” Audio reference: listen to professional sources such as Pronounce or Forvo for native speaker samples to hear the two-word boundary intonation.
Common errors: misplacing stress, pronouncing ‘Erlenmeyer’ as ‘ER-leen-my-ER’ or slurring the -meyer into a single syllable; mispronouncing ‘flask’ as ‘flaskk’ with extra consonant or softening the /æ/. Corrections: keep the two main parts separate with a clear boundary (ER-lən-MY-er) and finalize with a crisp /flæsk/. Practice the /ɜː/ vowel with rounded lips, and avoid turning /maɪə/ into /maɪəɹ/ in a single syllable. Listen to medical or chemistry instructors to model the two-stress pattern and consonant clarity.
In US, the ERL part uses /ɜːr/ with rhotic /r/ coloring; /maɪər/ keeps a clear long ‘i’ before a schwa. UK tends to a shorter /ɜː/ with less rhoticity in careful speech and a slightly crisper /flæsk/. Australian English aligns more with US vowel length but may feature a slightly flatter /ɜː/ and a broader /æ/. Across all, the /flæsk/ final is stable; the biggest variation is in the Erlenmeyer portion’s /ɜːr/ or /ɜː/ and whether the rhotic /r/ is pronounced. Aim for cross-dialect consistency in technical contexts by defaulting to /ˈɜːrlənˌmaɪər/ for Erlenmeyer and /flæsk/ for Flask.
The difficulty comes from the multi-syllabic, non-native vowel sequence in ‘Erlenmeyer’ and the tri-syllabic stress pattern. The initial /ɜːr/ vowel is unique to English and rhoticity adds complexity when speaking quickly. The /maɪər/ cluster involves a diphthong followed by a schwa, which can blur in fast speech. Also, the two-stress structure requires clear boundary between parts. Practice slowly, then speed up with deliberate articulation to maintain accuracy.
In standard American and British usage, the primary stress lands on the first syllable (ER-lən), while the secondary stress falls on the ‘mey’ portion in ‘meyer’ (Erlen-MEY-er). So you say ER-lən-MY-er, with the main emphasis on the first syllable and a noticeable secondary prominence on the third syllable of the word. The transition to Flask at the end keeps the flow intact without adding extra emphasis. IPA: /ˈɜːrlənˌmaɪər/ for Erlenmeyer; /flæsk/ for Flask.

- US: rhotic /r/ after vowels; ensure clear /ɜːr/ in the first syllable; keep /maɪər/ distinct with a mid schwa after /ɪ/; the final /æ/ in Flask should be short and crisp. - UK: less rhoticity in careful speech; focus on maintaining /ɜː/ sound and a crisp /ˈflæsk/ ending; the /ə/ between /n/ and /maɪ/ may be slightly stronger. - AU: similar to US but with flatter vowels and sometimes stronger /ɜː/; ensure non- rhotic ending in non-final contexts. IPA references: US /ˈɜːrlənˌmaɪər flæsk/, UK /ˈɜːlənˌmaɪə flæsk/. - General tip: practice in minimal pairs with neutral words to cement the boundary and reduce slurring across the two-word noun. - Use tongue-height control: /ɜː/ high-mid back, /l/ dark, /m/ bilabial, /aɪə/ glide sequence, final /flæsk/ with a short /æ/.
Erlenmeyer Flask derives from the inventor’s surname Erlenmeyer, a German chemist Friedrich Adolf Konstantin Erlenmeyer, who designed the conical, narrow-neck flask in the late 19th century. The word ‘Erlenmeyer’ itself originates from German toponymic naming practices, combining the family name with the concept of a flask. The term first appears in scientific texts around the 1860s–1880s as laboratories adopted standardized glassware. The suffix ‘Flask’ labels the vessel type; together, the name became a universal descriptor in chemistry education and practice. Over time, English usage stabilized the two-word form, with ‘Erlenmeyer flask’ appearing in textbooks, lab manuals, and procurement catalogs from the early 20th century onward. The design’s continuing relevance in modern laboratories reinforces its status as a canonical piece of glassware, even as materials science and alternative labware emerge. In contemporary usage, the name references both the physical object and its historical origin, maintaining the link to its inventor while remaining a generic term for conical flasks in many countries.
