Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'болезнь движения' (calque) – the standard term is 'морская болезнь' (sea sickness), which is used for all motion sickness, not just at sea.
- Do not confuse with 'укачивание' (the process/state of being rocked to sickness), which is the action, not the condition's name.
Common Mistakes
- Using as a countable noun (*I had a motion sickness). Correct: I had motion sickness. / I had a bout of motion sickness.
- Confusing with 'altitude sickness' or 'food poisoning', which have different causes.
