Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation with 'компонент' for non-systematic parts (e.g., 'part of a story' is not typically a 'component').
- Don't confuse with 'compound' (соединение, составное вещество). 'Component' is a part *within* a compound or system.
- In Russian, 'комплектующее' is a closer match for a manufactured spare part, while 'component' is broader.
Common Mistakes
- Misspelling as 'componant'.
- Using 'component' for a minor or insignificant part where 'part' or 'piece' is more natural.
- Incorrect pluralisation: 'components' (standard).
