Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid a direct word-for-word translation like 'плохой холестерин' as it is the correct calque; the trap is not recognising it as a fixed compound term for 'LDL'.
- Do not confuse with general 'high cholesterol' (высокий уровень холестерина), which includes other types.
Common Mistakes
- Using 'bad cholesterol' as an adjective without a noun (e.g., 'He is bad cholesterol' is wrong).
- Confusing it with dietary cholesterol from food, which is a related but different concept.
