Fissure is pronounced FISH-ur (/ˈfɪʃɚ/). It has two syllables (Fis-sure), with the stress on "Fis". Fissure is a narrow opening or groove, often a natural crack or split in rock, skin, or other surfaces. In anatomy it denotes a furrow or groove, such as a fissure in the brain or lungs. The term is used in geology, biology, and medicine to describe elongated separations, usually with sharp, irregular edges.

US/UK/AU pronunciation centers on two syllables with the first stressed: /ˈfɪʃər/ (US) and /ˈfɪʃə/ (UK) with the final vowel often reduced in fast speech. The initial consonants are /f/ and /ʃ/; the middle is a short /ɪ/ or /ɪə/ depending on dialect; the final is a schwa or syllabic /ɚ/ in US. You can model as FISS-ər: feel the air with /f/ lips, then the /ɪ/ tongue high, then /ʃ/ blade behind teeth, and finally a relaxed, neutral vowel. Audio reference: think of “fisher” with a soft mouth position and a silent-ish last consonant in rapid speech.
Common errors: 1) treating /ɪ/ as a long vowel or diphthong, producing /ˈfɪːʒər/ instead of short /ɪ/; 2) mispronouncing the second syllable as /ˈfɪʃuːr/ with a tense /uː/; 3) substituting /s/ for /ʃ/ resulting in /ˈfɪsər/. Correction: keep /ʃ/ as the mid-palatal fricative after /f/, keep /ɪ/ short, and relax the final vowel to a weak /ə/ or schwar; practice with minimal pairs like fissure vs fiss-ure variations and record for feedback.
US tends to pronounce as /ˈfɪʃər/ with rhotic final /r/ and a reduced final vowel; UK often /ˈfɪʃə/ with non-rhotic /r/ and a reduced ending; Australian usually /ˈfɪs.tʃəd/ or /ˈfɪʃ.ə/ with a slightly more rounded vowel in the second syllable and less conspicuous /r/ in non-rhotic speech. The key difference is rhoticity and vowel reduction: US keeps a rhotic /r/; UK and AU may reduce the second syllable to /ə/ or /ə/. IPA references: US /ˈfɪʃər/, UK /ˈfɪʃə/, AU /ˈfɪs.tʃə(ː)/.
The difficulty lies in the /ʃ/ following /f/ and the final reduced vowel. The sequence /fɪ/ requires precise tongue position at the teeth-alveolar boundary, then the mid-palatal /ʃ/ requires a high, retracted tongue blade; finally, the weak /ə/ can be hard to hear when spoken quickly. Maintaining the contrast with similar sounds like /fɪs/ and /fɪʃ/ is essential. Also, the subtle rhotic /r/ in American speech can complicate the last syllable. Practice focusing on the transition: /f/ → /ɪ/ → /ʃ/ → /ər/.
A key nuance is the potential final consonant length variation. In careful speech you may hear a light pronunciation of the second syllable ending in a soft schwa with minimal voicing, especially in British English, making /ˈfɪʃə/ rather than a full /ˈfɪʃər/. In American English, the final may carry a pronounced /ɚ/ or /ər/ depending on speaker, but the broad sound remains /ˈfɪʃər/. Awareness of this ending helps avoid overemphasizing a hard /r/ in non-rhotic dialects.

Fissure comes from the Latin fissura, from figere 'to split, to fix' in the sense of a cleft or crack. The root is found in Late Latin fissura, likely derived from the verb findere, meaning to split or divide. The English adoption early on preserved the sense of a long, narrow opening, often geological or anatomical. In medical contexts from the 18th century onward, fissure described pathological splits (e.g., anal fissure) as well as natural anatomical grooves. The word evolved to cover diverse domains: geology (rock fissures), anatomy (fissures of the brain or lung), botany (fissure-like splits in seeds), and general use for any narrow crevice. The first known use in English dates to the 17th century, with cognates appearing in various Romance languages; the Latin lineage through fissus ‘split’ remains central to its meaning across disciplines.
