Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'интерфейс' for all meanings; for abstract 'point of contact', use 'точка соприкосновения' or 'связующее звено'. The verb 'to interface' is often best translated as 'взаимодействовать' or 'сопрягать', not 'интерфейсить'.
Common Mistakes
- Using 'interface' as a verb in very formal writing where 'interact' or 'communicate' might be preferable. Confusing 'interface' (interaction point) with 'surface' (just the outside).
