- Avoid direct translation with 'равновесие' in all contexts; use 'баланс' for market contexts and 'уравновешенность' for emotional states. 'Equilibrium' is more technical.
Common Mistakes
- Using 'equilibrium' for simple physical balance (use 'balance'), mispronouncing /kw/ as /k/, using 'an equilibrium' incorrectly (it's usually 'an equilibrium' due to the vowel sound).
