2 syllables: feld, spar. Stress on feld.
FELD-spahr
/ˈfɛldˌspɑɹ/
feldspar is pronounced FELD-spahr (/ˈfɛldˌspɑɹ/). It has two syllables (feld-spar), with the stress on "feld". Feldspar is a groups of rock-forming minerals, primarily potassium- and sodium-rich aluminosilicates. The term describes a family of minerals that constitute a large portion of the Earth's crust and are key constituents in igneous rocks. In geology and material science, feldspars influence texture and melting behavior in rocks and ceramics.

- Misplacing the primary stress on feld- and making the second syllable trivial. Focus on two clear syllables: FELD-SPAR, not fel-dspar. - Blurring the /ld/ into an /l/ or /d/ blend; ensure a clean /l/ then a released /d/ before /s/. - Not articulating the /sp/ cluster crisply; practice a quick but separate /s/ and /p/ with a short pause before /ɑː/ or /ɑr/ depending on accent. - Vowel length in the second syllable; US rhotic /ɑr/ vs UK/AU /ɑː/ can cause miscue; aim for a stable, single second-syllable nucleus.
"The granite sample contains visible feldspar crystals."
"Geologists dated the rock using feldspar-to-mleating analyses."
"Feldspar minerals are essential components of many ceramic glazes."
Say it as FELD-spahr, with the primary stress on FELD. The first syllable rhymes with “belt” and the second syllable sounds like “spare” without the /eɚ/ ending. IPA: US/UK/AU: ˈfɛldˌspɑr (US), ˈfɛldˌspɑː (UK/AU). Picture the mouth forming a short, sharp /f/ and /l/ cluster, then a clear /d/, followed by a rounded back vowel in the second syllable. Quick tip: keep the /s/ as a crisp sibilant between /d/ and /p/.
Mistakes often involve misplacing the stress and mispronouncing the second syllable. Common errors: saying /ˈfɛl(d)spar/ with an extra consonant or running /sp/ as a cluster without clear separation. Another frequent error is turning /ɑr/ into an r-colored vowel in non-rhotic accents. Correction: emphasize the two-syllable structure with a clear /d/ closure before the /sp/ cluster, and keep the second syllable as /spɑr/ rather than /spɑːr/ in non-rhotic contexts, maintaining crisp /s/ and /p/ timing.
US tends to preserve /ˈfɛldˌspɑr/ with rhotic /r/. UK/AU typically use /ˈfɛldˌspɑː/ with non-rhoticity, so the final /r/ is not pronounced. Vowel quality may vary: US often has a slightly shorter /ɪ/ or clear /ɛ/, while UK/AU may lengthen the second syllable with /ɑː/. In general, the main difference is rhoticity and vowel length in the second syllable; the consonants remain /f/, /l/, /d/, /s/, /p/.
Two phonetic challenges: the /ld/ cluster after the initial /f/ and the /spɑr/ sequence, which requires rapid coordination of /s/ and /p/ without creating a separate syllable. Also, vowel quality in /ɛ/ vs /eɪ/ can be tricky in different accents. To ease difficulty, practice separating the segments: FELD + SPAR, ensuring the /d/ fully releases before /s/ starts, and maintain equal timing between syllables for a two-beat rhythm.
No, the /d/ is pronounced in standard English pronunciations. The concern is not silent letters but the fast transition from /ld/ to /sp/. In careful speech you’ll hear a distinct /d/ closure before the /s/ onset in both American and British varieties; in rapid speech it may blur slightly, but it should not disappear. A clear release on /d/ helps prevent a misperception of /l/ + /s/ as a single blend.

- US: rhotic /r/ at the end; ensure a pronounced but non-drawn-out /ɑr/. Mouth slightly rounded in the second syllable; keep /s/ crisp between /d/ and /p/. - UK: no final /r/; lengthen the second vowel to /ɑː/ and maintain clear /s/ and /p/ onset; keep tongue relaxed but precise. - AU: similar to UK in vowel length; slight vowel lifting can occur; maintain independent /d/ release and a crisp /s/. - IPA cues: US /ˈfɛldˌspɑr/, UK/AU /ˈfɛldˌspɑː/.
The word feldspar comes from the German feldspat, first recorded in the 1800s, from feld meaning 'field' and spat meaning 'spatula' or 'splay'—a nod to its habit of breaking along feldspathic planes. The term was adopted into English mineralogy to contrast nonfeldspathic minerals. The root feld- traces to the Proto-Germanic felþ- meaning ‘field’, while -spar derives from Middle English spar, related to stone or rock. Over centuries, feldspar broadened from describing a single mineral to a whole family of aluminosilicate minerals including orthoclase, plagioclase, and microcline, reflecting shared crystallography (tetragonal or monoclinic) and framework structures (SiO4 tetrahedra linked by Al and alkali ions). First recognized as a chemically related class in 18th–19th century mineralogical surveys, feldspar’s classification evolved with advances in X-ray diffraction and optical crystallography, cementing feldspar as a cornerstone term in geology and petrology.
