Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'шпора' (the noun for riding spur) for most verb contexts. For 'spur growth', use 'стимулировать рост', not a literal translation.
- The idiom 'on the spur of the moment' corresponds to 'сгоряча' or 'спонтанно', not a phrase involving 'момент' directly.
Common Mistakes
- Incorrect: 'The news spurred him for working harder.' Correct: '...spurred him to work harder / into working harder.'
- Confusing 'spur' (external stimulus) with 'motivate' (which can be internal).
