Learning

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not translate literally as 'действие колена' – this is nonsense. The correct technical term is 'независимая подвеска на продольных рычагах' or 'подвеска 'коленного' типа' (historical).

Common Mistakes

  • Using it to describe a person's physical movement (e.g., 'good knee action in the dance') – this is highly non-standard and marked.
  • Thinking it is a current technical term.
