Inbus or Imbus – Which One Is Correct?

You’ve probably heard both versions: some say imbus key, others say inbus key. But which one is more accurate? Let’s take a closer look, because language often holds some surprising twists.

The etymology – where does “Inbus” come from?
The word originates from the German abbreviation INBUS: Innensechskantschraube Bauer und Schaurte (roughly: internal hexagon screw, Bauer & Schaurte being the manufacturer). In Germany, it is still known as Inbus-Schlüssel.

In Hungarian, however, the pronunciation and adaptation of the word led to the widespread form imbusz.

Imbus in Hungarian spelling
It’s important to note that the form imbusz appears in Hungarian spelling dictionaries and is considered the standard in everyday language. The Inbus form is etymologically correct, but in Hungarian context, the imbusz form has taken root.

So which one should we use?

• In everyday speech, imbusz is widely understood and accepted.

• In technical or brand-related contexts, it may make sense to mention the original Inbus form.

• The key is understanding that both versions have their place: Inbus is the origin, imbusz is the Hungarian adaptation.

Conclusion
The word started as Inbus, but in Hungarian, the form imbusz became standard. Rather than a question of “right or wrong”, it’s an example of how language evolves naturally.
