Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'подъём' (which is more general for 'rise' or 'ascent'). 'Upsurge' implies a sharper, more dynamic and often less predictable increase. Closer to 'всплеск', 'резкий рост'.
Common Mistakes
- Using 'on' instead of 'in' (e.g., 'upsurge on violence' – incorrect). Using it for very slow, gradual increases.
