Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'кальций' (calcium). The Russian anatomical term is 'пяточная кость' (pyatochnaya kost'), which translates directly to 'heel bone'. 'Calcaneum' is the specific Latin-derived international term.
Common Mistakes
- Misspelling as 'calcanium' or 'calcaneium'.
- Using it in everyday conversation where 'heel' is sufficient.
- Incorrect pluralisation ('calcaneums' is acceptable, but 'calcanea' is the classical plural).
