Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation for idioms (e.g., 'красная нить' is not 'red thread' but 'common thread'). 'Red Square' is a proper name. 'Red' for 'красивый' is archaic and not used.
Common Mistakes
- Using 'red' to describe 'brown' hair (should be 'auburn' or 'chestnut'). Confusing 'red' with 'pink' in descriptive language. Overusing 'red' for anger instead of more precise words like 'furious' or 'enraged'.
