Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with "циклотрон" (cyclotron - a type of particle accelerator). The Russian equivalent would be a highly specific medical term like "циклотом" or описательно "инструмент для рассечения цилиарной мышцы".
Common Mistakes
- Spelling: cyclotome vs. cyclotron
- Assuming it is a general term for any circular cutter.
- Assuming it is a modern, commonly used word.
