Memory Aids

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid direct translation as 'подпорки' (props) in abstract contexts, which is too physical. For abstract senses, use 'основы', 'фундаментальные принципы', 'базис'. For physical, 'опоры', 'несущие конструкции'.

Common Mistakes

  • Using as a singular ('an underpinning') is uncommon. Treat as plural. Confusing with 'understandings'. Using in informal contexts where 'basics' or 'reasons' would suffice.
