Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating it literally as 'закон мидян и персов' without context, as it may not be understood. The conceptual equivalent is 'неписаный закон' or 'незыблемое правило', but these lack the historical flavor. The phrase 'догма' or 'непреложный закон' are closer in tone.
Common Mistakes
- Incorrect article use (e.g., 'law of Medes...'). The definite article 'the' is required for both peoples. | Capitalization: 'Medes' and 'Persians' are proper nouns and should be capitalized. | Using it to describe something merely difficult, rather than truly unchangeable.
