Common Pitfalls
Translation Traps (for Russian speakers)
- The Russian borrowing 'смог' is a false friend for the English modal verb 'can' in the past tense ('could' = 'мог').
- Do not confuse with the English verb 'smog' (rare, to be affected by smog), which is not used in Russian.
Common Mistakes
- Using 'smog' to refer to any fog or mist (must involve pollution).
- Incorrect pluralisation ('smogs' is rare but acceptable when referring to multiple events).

FAQ
Frequently Asked Questions
No, the term was coined in the early 20th century, but severe smog events like the London Great Smog of 1952 highlighted its dangers historically.
Smog specifically implies harmful pollution (from vehicles, industry), while haze can be caused by natural particles like dust or moisture and may be less toxic.
Yes, but it is rare and informal (e.g., 'The city gets smogged in'). The adjective 'smoggy' and noun 'smog' are far more common.
Yes. The two classic types are 'London smog' (sulphurous, from coal) and 'Los Angeles smog' (photochemical, from vehicle emissions reacting with sunlight).
