- Do not translate literally as *"жилет жизни". The correct Russian equivalent is "спасательный жилет".
- Avoid confusing with "waistcoat" (which is also "жилет") – the key component is "спасательный".
- The phrase "to wear a life vest" must be translated with the verb "надевать/носить", not "одевать" in the reflexive sense.
Common Mistakes
- Incorrect: *"He put on his life jacket vest." (redundant) Correct: "He put on his life vest/life jacket."
- Incorrect (BrE context): *"Make sure your life vest is fastened." (understood, but non-idiomatic) Correct: "Make sure your life jacket is fastened."
- Incorrect: *"swimming vest" (ambiguous, could be a training aid).
