Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'фактически', which is more general. 'De facto' is more formal and implies a contrast with an official norm ('де-юре').
- Do not use 'де-факто' in casual Russian speech; it is a direct loan and sounds overly formal.
Common Mistakes
- Misspelling as 'defacto' (should be two words).
- Confusing with 'de jure'.
- Using it in overly casual contexts where 'unofficial' or 'actual' would be more natural.
