Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid calquing word-for-word as "скала падает" for the noun phrase. Use "обвал (породы)", "камнепад".
  • The plural 'falls' is essential for the event noun; 'rock fall' can be singular for one event.
  • Do not confuse with 'waterfall' which is also 'falls' (e.g., Niagara Falls).

Common Mistakes

  • Incorrect singular/verb agreement in noun phrase: 'A rock falls is dangerous.' (Correct: 'A rock fall is...')
  • Using as a continuous verb unnecessarily: 'Rocks are falling' is often more natural than 'Rock falls are happening.'
