Common Pitfalls
Translation Traps (for Russian speakers)
- Не переводите буквально как "задний вид". В техническом контексте: "задний прицел" (оружие) или "обратная визирка" (геодезия). В переносном смысле соответствует "ретроспектива" или "взгляд в прошлое", но звучит непривычно.
Common Mistakes
- Using it as a common synonym for 'hindsight' in everyday speech. Confusing it with 'foresight' (the opposite).
