Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'превышение' in all contexts, as it is much narrower. 'Exceedance' is a specific, measured event, not a general act.
Common Mistakes
- Using it as an uncountable noun (e.g., 'There was much exceedance'). It is typically countable.
- Confusing it with the more general 'excess'.
- Using it in non-technical contexts where 'breach' or 'going over' would be more natural.
