Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'предсказуемость' for all contexts; in English, it can sound more formal and systemic.
- In casual negative contexts ('boring predictability'), consider 'предсказуемость' but also phrases like 'отсутствие сюрпризов' (lack of surprises).
Common Mistakes
- Misspelling as 'predictibility' (missing 'a').
- Using 'prediction' (the act) instead of 'predictability' (the quality).
- Overusing in casual speech where 'routine' or 'reliability' might be more natural.
