4 syllables: en, do, plas, mic. Stress on plas.
en-duh-PLAZ-mik
/ˌɛn.dəˈplæz.mɪk/
endoplasmic is pronounced en-duh-PLAZ-mik (/ˌɛn.dəˈplæz.mɪk/). It has four syllables (en-do-plas-mic), with the stress on "plas". Endoplasmic is an adjective relating to or characteristic of the endoplasm, the inner part of a cell’s cytoplasm. In biology, it describes structures associated with or forming the endoplasmic reticulum. The term is used primarily in cellular biology and biochemistry to specify components situated inside cells rather than on their membranes.

"Scientists studied the endoplasmic network to understand protein synthesis within the cell."
"The researchers focused on the endoplasmic reticulum and its endoplasmic reticulum tubules."
"Endoplasmic processes influence how proteins fold and traffic through the cytoplasm."
Pronounce en-doh-PLAS-mik with primary stress on the second syllable: /ˌɛn.dəˈplæz.mɪk/. The first syllable is light, the second carries the main stress, and the final -mic is pronounced with a short i, as in 'mic.' Lip rounding is subtle at the 'plas' syllable, and the 'plas' contains the 'a' as in 'cat.' You’ll hear a crisp stop before the 'plas' cluster in careful speech.
Common errors include stressing the wrong syllable (placing stress on the first or third instead of the second), mispronouncing the ‘plas’ as ‘plaz’ or elongating the last syllable ‘-mic.’ Another pitfall is reducing the middle vowel to a schwa in rapid speech. Correct by emphasizing the second syllable with /ˈplæz/ and keeping the final /mɪk/ short and clipped. Practice in slow tempo, then increase speed while maintaining the stress pattern.
Across US/UK/AU, the primary difference is in vowel quality and rhoticity. US and UK share /ˌɛn.dəˈplæz.mɪk/; US may reduce the second syllable slightly more, while UK tends toward a crisper /ˈɛndəˌplæz.mɪk/ feel. Australian speakers typically retain a clear version with less rhotic influence, maintaining /ˌɛn.dəˈplæz.mɪk/ but with slightly broader vowels in stressed syllables. Consonants are generally consistent, but vowel quality and rhythm shift subtly by region.
The difficulty lies in the three-syllable pattern with a secondary stress shift and the ‘plas’ cluster, which requires precise mouth positioning: the /pl/ combination demands a quick, firm stop then a rounded /æ/ vowel, followed by /z/ or /z.m/ in rapid delivery. The /ɪk/ ending is short, so the final consonant cluster should stay tight. Native-like accuracy comes from slow, deliberate practice of the -plas- sequence and consistent final syllable shortening.
A useful tip is to chunk the word as en-doh-PLAS-mik, with a clear hijacked beat on the second syllable. Imagine checking with your tongue: the tip quickly taps the alveolar ridge for /d/ then glides into /ə/ or /ɚ/ sound before a strong /plæz/ onset. Keeping the vowel in 'plas' compact helps avoid turning it into 'plase' or 'plash.' This helps maintain the exact stress pattern and crisp final /mɪk/.

-US: rhotic US accent often keeps the 'r' neutral; but 'endoplasmic' has no r; rely on clear /ɪ/ and /ə/ reductions in the first two syllables. -UK: crisper vowels, slightly fronted /e/ in the first syllable and a tighter /ə/; maintain non-rhoticity. -AU: more open vowels, a balanced /ɪ/ and /ə/; keep the 'plas' sequence sharp. IPA references: US /ˌɛn.dəˈplæz.mɪk/, UK /ˌɛn.dəˈplæz.mɪk/, AU /ˌɛn.dəˈplæz.mɪk/.
Endoplasmic derives from the Greek endon (inside, within) + plasma (formed or molded substance, or cytoplasm) with -ic as a typical English adjectival ending. The prefix endo- signals ‘within’ or ‘inside,’ while plasma in this scientific context refers to the living material within a cell, particularly the cytoplasm. The term was coined in 19th–20th-century biology as researchers increasingly named subcellular structures. The modern meaning centers on internal cytoplasmic elements associated with the endoplasmic reticulum system, and it entered scientific usage as microscopy and cell fractionation advanced. Early histologists and cytologists used endoplasmic to distinguish intracytoplasmic components from organelles located toward the cell cortex or membrane. Over time, endoplasmic gained traction in biochemistry and cell biology, especially in discussions of intracellular transport, protein synthesis, and organelle function. First known uses appear in mid-20th-century texts describing cellular compartments, with subsequent proliferation in molecular biology literature as endoplasmic reticulum became central to understanding secretory pathways and organelle networks.
