Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid direct translation 'качающаяся спина' or 'раскачивающаяся назад'. Use specific term 'лордоз' for the medical condition or 'провисшая спина' for the descriptive sense in animals.

Common Mistakes

  • Using 'sway-back' to describe general back pain in humans (too specific).
  • Confusing it with 'hunchback' (kyphosis) which is the opposite curvature.
