Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'детекция' (extremely rare/technical). Use 'обнаружение', 'выявление'.
- Don't confuse with 'детектив' (detective). 'Detection' is the process, not the person.
- In medical contexts, 'early detection' translates as 'ранняя диагностика' (diagnosis), not 'обнаружение'.
Common Mistakes
- Using 'detection' for simple 'notice' in casual contexts (overly formal).
- Misspelling as 'detaction'.
- Incorrect preposition: 'detection for' instead of 'detection of'.

FAQ
Frequently Asked Questions
No. While often used for finding problems (fraud, disease, threats), it is also used neutrally in science and technology (detection of gravitational waves, detection of a signal).
'Detection' often implies a deliberate search or use of a system/technology to find something hidden or not obvious. 'Discovery' can be more general, sometimes accidental, and often refers to finding something entirely new.
Typically uncountable (e.g., 'early detection is key'). It can be countable when referring to specific instances or types (e.g., 'several detections were made', 'various fraud detections'), but this is less common.
No significant difference in usage. The spelling and core meaning are identical. Minor differences may exist in specific technical jargon of certain industries.
