Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'code' as 'код' for 'cipher' when meaning 'cipher' is specifically 'шифр'. 'Source code' is 'исходный код', not 'источник код'. 'Area code' is 'телефонный код', not 'площадь код'.
Common Mistakes
- Using 'code' as a countable noun incorrectly (e.g., 'a code' vs. 'some code' for software). Confusing 'code' (rules) with 'law' (single statute).
