2 syllables: cus, pid. Stress on cus.
/ˈkʌspɪd/
Say it backCuspid is a term used in anatomy and dentistry to denote a pointy tooth, typically the canine. It also appears in geometry as a cusp point on a curve. The word carries a clinical, technical tone and is most commonly encountered in medical or scholarly contexts rather than everyday speech.
"The dentist noted a prominent cuspid on the upper jaw requiring careful restoration."
"In anatomy lectures, the term cuspid is used to describe the canine tooth’s sharp cusp."
"The researcher mapped the cuspid points along the tooth row for the dental study."
CUS-pid, with stress on the first syllable. IPA: US ˈkʌs.pɪd, UK ˈkʌs.pɪd, AU ˈkʌs.pɪd. Start with a short, lax 'k' then the 'ʌ' as in 'cut', followed by a light 's' and the 'p' onset of the second syllable. The second syllable uses a short 'ɪ' as in 'bid' and ends with a clear 'd'. Guidance: pronounce as two clean syllables, avoiding vowel elongation. Audio reference: you can check major dictionaries or Forvo for speaker variants.
Common errors include turning 'cuspid' into two syllables with a prolonged 'u' (CUSS-pid) or merging the 's' and 'p' into a coarticulated cluster that sounds like 'kus-pid' with a blurred stop. Correct by maintaining crisp syllable boundaries: kʌs.pɪd, with a light, unpalatalized 's' and a distinct 'p' onset in the second syllable. Ensure the 'd' is voiced, not a tapped or glottal stop. Practice by saying ‘cussed’ then ‘pid’ separately before merging.
In US and UK, the initial vowel is the short ‘ʌ’ as in 'cut', with rhoticity not affecting the word; both typically produce ˈkʌs.pɪd. Australian speakers may exhibit a slightly more centralized vowel in the first syllable, sometimes approaching ˈkəs.pɪd, but most speakers retain the /ʌ/ sound. Final consonants remain /d/ in all. The main differences are subtle vowel quality and vowel length; avoid rhotic misinterpretations since the word does not carry r-coloration in non-rhotic accents. Overall, expect near-identical two-syllable pronunciation across regions.
The difficulty stems from the short, clipped vowels and the adjacent 's' and 'p' cluster across syllables, requiring precise timing to avoid a blending error (kus-pid). The second syllable begins with a voiceless stop /p/ which can rush if you’re not pausing. Additionally, maintaining a crisp /d/ at the end can be challenging if you speak quickly. Focus on keeping two distinct syllables with a clear onset of /p/ and final voiced /d/.
A unique feature of cuspid is the second syllable onset with a clean /p/ before /ɪ/; avoid coalescing the /s/ with the /p/ into a single sibilant. Confirm you’re producing an audible stop onset on the second syllable, not a vowel glide. Mouth position: keep lips rounded slightly for /ʌ/ and release into /p/ with a brief aspiration, then move to /ɪ/ and finally /d/.

Cuspid derives from Latin cuspi- ‘pointed’ from cuspis ‘point, spear’ (also the root of cusp). The term entered English via medical Latin usage in the 18th and 19th centuries as anatomists described tooth morphology and cusp-like projections on dental surfaces. Its broader sense in geometry, referring to a pointed end of a curve, later aligned with the same Latin root in mathematical descriptions of sharp tips. The word is composed of the root cuspid- plus the standard English suffix -id, yielding a noun that designates a pointed projection. First known English uses appear in anatomical texts as physicians and dentists systematized the nomenclature of crown morphology, including cusps and cuspid teeth, around the late 1700s to early 1800s. Over time, “cuspid” has retained its precise, clinical connotation, and in some contexts is synonymous with “canine cusp.” The evolution of its meaning parallels the linguistics of Latin-derived medical vocabulary, where geometric and dental terms shared a common emphasis on pointed forms and projections.
