Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid using 'world' for 'light' (as in 'свет'). 'The world' is мир/свет in the sense of 'society', but not a source of illumination.
- Do not confuse 'world' with 'age' or 'century' (e.g., 'in the modern world' is 'в современном мире', not 'в современном веке').
Common Mistakes
- Using 'world' as a countable noun incorrectly (e.g., 'a world' is usually metaphorical, not a separate planet).
- Incorrect preposition: 'in the world' (location/domain) vs. 'around the world' (movement/scope).
- Overusing 'all the world' instead of more natural 'everyone' or 'the whole world'.
