For example Gödel belongs to the generation of
logicians that use the term "undecidable".
In German the term is translated to "unentscheidbar":

Über formal unentscheidbare Sätze der Principia Mathematica und 
verwandter Systeme I" ("On Formally Undecidable Propositions of 
Principia Mathematica and Related Systems I")
