Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'предположение' (assumption/supposition) in all contexts. The negative connotation of arrogance is better translated as 'самоуверенность', 'наглость', or 'самомнение'. The legal term is 'презумпция'.
Common Mistakes
- Confusing 'presumption' with 'assumption' in formal writing (presumption is stronger, often with an implied basis or consequence).
- Using the countable noun without an article where one is needed: 'He acted on presumption' (correct) vs. 'He acted on a presumption' (also correct, but more specific).
