Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calques like 'мольный мяч' or 'мольный шар'. The noun is 'нафталин' or 'шарик от моли'. The verb is best translated as 'законсервировать', 'отложить на неопределенный срок', or 'поставить на прикол' (for ships).
Common Mistakes
- Using 'mothball' as a synonym for 'cancel' (it implies potential future use).
- Confusing 'mothball' (noun/verb) with 'moth' (the insect).
- Incorrect stress: it's MOTH-ball, not moth-BALL.
