Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid directly translating as 'функциональность' in all contexts. In Russian, 'функциональность' can sound overly technical in casual speech where 'возможности' (capabilities) or 'работа' (how it works) might be more natural.
Common Mistakes
- Using 'functionality' as a countable noun (e.g., 'three functionalities' is debated; 'three functions' or 'three features' is often preferred). Confusing it with 'function', which is more specific and countable.
