Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'стерилизовать' (correct) vs. 'стерильный' (sterile, adjective). Avoid direct translation for metaphorical use (e.g., 'sterilize the conversation' is not a common Russian metaphor).
Common Mistakes
- Confusing 'sterilize' (remove life) with 'sanitize' (reduce germs to safe levels). Using it for general cleaning instead of complete microbial elimination.
- Incorrect: 'I sterilized the kitchen floor.' (Overkill) Correct: 'I disinfected the kitchen floor.'
