Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'импрегнировать' (hyper-formal/obsolete). For literal 'make pregnant', use 'оплодотворять' or 'осеменять'. For metaphorical 'saturate', use 'пропитывать', 'насыщать', 'проникать'.
Common Mistakes
- Confusing 'impregnate' with 'impregnable' (unable to be captured). Using it informally for 'pregnant' (e.g., 'She is impregnated' is incorrect; use 'She is pregnant'). Overusing the metaphorical sense.
