Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'фигура' (figure).
- It is a specific type of crack, not a general 'трещина' for small surface cracks. Often corresponds to 'трещина', 'расщелина', or in medicine 'фистула' (fistula, which is different), so check context.
Common Mistakes
- Mispronouncing as /faɪˈʒʊr/ or /ˈfɪs.jʊr/.
- Using it for a small, shallow crack (better: 'crack' or 'chip').
- Confusing spelling with 'fisher'.
