Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as "рамка" for pictures; use "frame". "Rim" is for 3D, circular edges. "Край" is more general; "rim" is specifically a raised/defining edge.
Common Mistakes
- Using "rim" for a flat border (e.g., of a country). Confusing "rim" with "frame" (spectacle rim is correct).
