Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid a direct word-for-word translation ('прыгающий Джек'), which is meaningless. The established translation is 'прыжки с разведением рук и ног' or the borrowed term 'джампинг джек'. The toy sense is 'прыгун' or 'плясовая кукла'.
- The word 'jack' here is not a name but a generic term (from the toy).
Common Mistakes
- Incorrect singular/plural: 'a jumping jack' (correct) vs. 'a jump jack' or 'a jumping jacks' (incorrect).
- Spelling: 'jumpingjack' (should be two words or hyphenated 'jumping-jack').
