Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation as 'пропорциональный' alone; it misses the specific context of adjusting payments/charges over time. Better: 'рассчитанный пропорционально (периоду)' or 'распределённый пропорционально'.
- Do not confuse with 'pro-rated' (hyphenated variant is less common but acceptable).
Common Mistakes
- Using 'prorated' for non-proportional divisions (e.g., 'The cake was prorated among the children').
- Misspelling as 'pro-rated', 'pro rated', or 'prorata'.
- Using it as a noun (e.g., 'I received my prorate') instead of an adjective or verb.
