Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as just 'грудная клетка' in all contexts where 'chest' is meant. 'Rib cage' is specifically the bony structure. For the external chest area, 'chest' is more appropriate.
Common Mistakes
- Using 'chest' and 'rib cage' interchangeably in technical writing. 'My rib cage hurts' is fine, but 'He has a hairy rib cage' is incorrect.
- Misspelling as 'ribcage' (though sometimes accepted, standard is two words).
