Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating directly as 'профи' (slang for professional). Correct equivalents are 'умение', 'навык', or 'владение' (for languages).
- Do not confuse with 'профессионализм' (professionalism), which includes ethical conduct, not just skill.
Common Mistakes
- Using 'proficiency' to mean 'efficiency' (e.g., 'proficiency of the machine' is wrong).
- Incorrect preposition: 'proficiency for' instead of 'proficiency in/at/with'.
- Using it as a countable noun (e.g., 'proficiencies' is rare and usually avoided).
