Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation 'пока-пока' in adult formal contexts as English 'bye-bye' is much more childish.
- Do not confuse with 'бай-бай' (lullaby) - it's a false friend.
Common Mistakes
- Using 'bye-bye' in professional emails or meetings.
- Overusing with adult peers, which can sound patronising or immature.
