It is called the « Unschärferelation ». Some people prefer that to the english version because uncertainty makes you think that if you made better measurements, you wouldn’t get this uncertainty, which is not the case. In fact, it is better to think about it as relation between the dispersion of the momentums and the dispersion of the positions of a particle, which product has to be greater than $\frac{\hbar}{2}$. In other words it is all about the relation of the unsharpness of these two distributions. That’s why « unsharpness relation » seems twoto describe it better than « uncertainty principle ».
