Common Pitfalls
Translation Traps (for Russian speakers)
- Не путать с 'дефензива' (разг., редкое). Основной перевод — 'защита'. В юридическом контексте — 'защита' (сторона в суде), а не 'оправдание'. 'Self-defense' — 'самооборона', не 'самозащита' (более узкий контекст).
Common Mistakes
- Using 'defense' as a verb (the verb is 'defend'). Confusing 'defense' (protection) with 'offense' (attack). Misspelling 'defense' as 'defence' in American contexts and vice versa.
