Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'подводный' for the financial metaphor; use 'обремененный долгами' or 'с отрицательным капиталом'. For 'underwater' as an adverb ('swim underwater'), use 'под водой', not 'подводно'.
Common Mistakes
- Using 'under the water' as an adjective (incorrect: 'an under the water camera'; correct: 'an underwater camera'). Confusing 'underwater' (adj/adv) with 'undersea' (adj, usually for things on the seabed).
