Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with Russian 'летучий' only. It covers broader instability (markets, temper). Russian 'нестабильный' or 'изменчивый' are closer for non-chemical contexts.
Common Mistakes
- Using 'volatile' to mean simply 'violent' (it's about unpredictability, not necessarily force). Incorrect: 'He was a volatile fighter.' Better: 'He had a volatile temper.'
