Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'иней' (hoarfrost) and 'изморозь' (rime) – all translate as 'frost' in general contexts.
- The verb 'морозить' is 'to freeze', not 'to frost'. 'To frost' is more specific: покрывать инеем.
Common Mistakes
- Using 'frost' as a general synonym for 'cold' (e.g., 'There is a strong frost today' is less idiomatic than 'It's very frosty today').
- Confusing 'frost' (ice crystals) with 'ice' (solid water).
