Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation to 'ригор' – it's a false friend. Use 'строгость', 'тщательность', 'суровость', or 'жесткость' depending on context.
- Do not confuse with 'vigour' (UK) / 'vigor' (US), which translates to 'энергия', 'сила'.
Common Mistakes
- Misspelling: 'rigourous' (incorrect). The adjective is 'rigorous'.
- Using in overly casual contexts where 'toughness' or 'difficulty' would be more natural.
- Confusing 'rigor' (strictness) with 'vigor' (energy).
