Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation with 'безответственный' in all contexts, as the English term can be stronger and more personal. The Russian word may sound more formal/administrative, while the English is a direct character judgement.
Common Mistakes
- Confusing spelling: 'irrisponsible' (incorrect). Using it as a noun (e.g., 'He is an irresponsible').
