Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

Avoid translating as 'сырые волокна' in all contexts; in textiles, 'необработанное волокно' is more accurate. In a dietary context, use 'пищевые волокна' or 'клетчатка'. The metaphorical use may not translate directly.

Common Mistakes

Using singular 'fiber' when referring to the material in bulk ('We import raw fiber'). The plural is standard. Confusing 'fibers' with 'fabrics'. Using it in everyday conversation where 'rough material' or simply 'fibre' would suffice.
