Since that which is Germanic cannot be 'Germanized', the term "Germanization" for the periods 1870-1918 and 1940-1945 should be understood as an adaptation of form or graphics to standard German as intended by the heads of state of the last German empires. The Anglo-Saxons speak here rather of 'prussification' to avoid confusion. Moreover, many Moselle toponyms, characteristic of the Franconian Lorraine dialect, also exist in Germany or Austria. For a Francophone, Merlebach is objectively no less Germanic than Merlenbach.
