Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid translating literally as 'сухой колодец' for the figurative sense; use 'пустая затея', 'провальное дело', or 'бесперспективный проект'. The literal term for a waterless well is 'сухая скважина'.

Common Mistakes

  • Using 'dry well' as an adjective (e.g., 'a dry well project' is acceptable, but 'the project was dry well' is not). Confusing it with 'dry run' (a rehearsal).
