Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating literally as 'тёмный фонарь', which would imply a lantern of dark colour. The functional aspect is key: 'фонарь с затвором' or 'потайной фонарь' is more accurate.
Common Mistakes
- Using it to describe a lantern that is not working or is simply black in colour.
- Assuming it is a common synonym for any old-fashioned lantern.
