Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with a general 'процесс' (process). It is a 'отросток' (росток, outgrowth). The key is the shape: 'крючковидный' (hook-shaped).
Common Mistakes
- Mispronouncing as 'un-SIN-ate' (correct: 'UN-sin-ate').
- Using it as a general term for any process.
- Confusing which bone it belongs to without specifying (e.g., 'the uncinate process' is ambiguous).
