Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'асфиксия' (noun). 'Asphyxiate' is a verb. The direct translation 'задушить' is correct but 'asphyxiate' is more formal/technical.
- Avoid using 'асфиксировать' as a direct calque; it is not standard Russian. Use 'вызвать асфиксию' or 'задушить'.
Common Mistakes
- Incorrect: 'He asphyxiated from the smoke.' (Better: 'He was asphyxiated by the smoke' or 'He asphyxiated on the smoke.')
- Confusing 'asphyxiate' (lack of oxygen) with 'strangle' (physical compression of the neck).
