Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid calquing from Russian 'хуже'. 'Worsen' is a verb, not a comparative adjective like 'хуже' (which is 'worse').
- Do not confuse with 'worry' or 'worship' due to similar initial 'wor-'.
- In transitive use, ensure the object is clear: 'It worsened the pain' not 'It worsened for the pain'.
Common Mistakes
- Using 'more worse' (double comparative; incorrect).
- Confusing 'worsen' with 'worsening' as an adjective: 'a worsen situation' (incorrect) vs. 'a worsening situation' (correct).
