Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'клык' (fang/canine of an animal) which has a more bestial connotation; 'cuspid' is a neutral anatomical term.
- Direct translation ('куспид') is meaningless in Russian; the correct equivalent is 'клык' (in human context) or 'клыковый зуб'.
Common Mistakes
- Pronouncing it as /ˈkjuːspɪd/ (like 'cute'); correct pronunciation has a short /ʌ/.
- Using it in everyday conversation where 'canine' is expected, causing confusion.
- Confusing it with 'bicuspid' (a premolar with two cusps).
