Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid directly translating 'снижение' as 'reduction' in all contexts. For a drop in temperature, 'drop' or 'fall' is often more natural. For a discount, 'discount' or 'price cut' is clearer than 'price reduction'.
- Do not confuse with 'редуктор' (a mechanical gearbox).
Common Mistakes
- Using 'reduction of' for people (incorrect: 'reduction of staff'; correct: 'reduction in staff' or 'reduction of staff numbers').
- Misspelling as 'reducation'.
- Using uncountable where countable is needed (e.g., 'a 20% reduction').
