Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating directly as 'земляной мост', which sounds odd. The standard term is 'сухопутный мост' or 'перешеек' (for an isthmus).
- The English term is a fixed compound noun, not a free combination.
Common Mistakes
- Incorrect: 'The lands bridged Asia and America.' (using 'bridge' as a verb for the land itself is rare)
- Spelling as one word: 'landbridge' (standard is two words).
