Common Pitfalls
Translation Traps (for Russian speakers)
- Not to be confused with 'охлаждение' (cooling down). No direct Russian equivalent. A descriptive translation like 'болезненное состояние от давки/скученности' is required.
Common Mistakes
- Misspelling as 'ochlesys' or 'ochlysis'. Using it as a synonym for simple claustrophobia or dislike of crowds. Trying to use it in modern conversation.
