Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not confuse with 'spina' (back) in all contexts; 'spine' is more specific. The figurative 'spine' (courage) is 'стержень' or 'характер', not directly 'спина'.

Common Mistakes

  • Using 'spine' to mean 'pain in the back' generally (prefer 'backache'). Confusing 'spinal' (adj.) with 'spiny' (having spines like a cactus).
