Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally as "C4". In technical contexts, use the specific Russian term for the concept (e.g., "взрывчатка C4", "разъём C4", "диаграмма C4"). In slang, a close equivalent might be "бомба" figuratively.
Common Mistakes
- Using 'C4' in general conversation expecting it to be understood.
- Confusing the explosive with the electrical connector based on context.
- Writing 'c4' in lowercase in technical documents where it is a proper name/standard.
