Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation from Russian 'гноиться' (to fester) for abstract concepts like 'problems'. It can sound overly literal and biological. Use 'усугубляться' or 'обостряться' conceptually.
- Do not confuse with 'ferment' (бродить), which relates to chemical process or excited activity.
Common Mistakes
- Incorrect: *'The happy memories festered in her mind.' (Fester is exclusively negative.)
- Incorrect: *'He festered about his decision.' (Fester is intransitive; use 'brooded' or 'agonised'.)
