How Do You Spell STUMPFF?
Pronunciation: [stˈʌmpf] (IPA) 
The spelling of "stumpff" might seem confusing at first glance, but it makes sense when you look at it phonetically. The IPA transcription for "stumpff" would be /stʌmpf/. The double "f" at the end indicates a voiceless bilabial fricative, which means that the sound is made by bringing the lips together and forcing air out without using the vocal cords. This kind of sound is common in German, which is where the name "Stumpff" is often found.
