Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid direct translation 'синий зуб'. It is universally 'Bluetooth' (Блютуз) in Russian.
  • Do not use 'беспроводной' alone as a synonym; it's too generic for 'Wi-Fi' etc.

Common Mistakes

  • Capitalising it in the middle of a sentence in non-technical writing (Bluetooth vs bluetooth).
  • Using it as a verb incorrectly ('I will bluetooth you the file' is informal).
  • Misspelling as 'blue-tooth' or 'blue tooth'.
