Common Pitfalls

- Do not confuse with 'fail' (неудача/провал). 'Flail' is about motion, not success/failure.
- The noun 'цеп' (for threshing) is a direct translation but highly archaic.
Common Mistakes
- Misspelling as 'flale' or 'fail'.
- Using it as a direct synonym for 'hit' or 'strike' (it emphasizes the motion, not the impact).
