German term introduced by Jacob, one of the Brothers Grimm, which we could translate by altering the sound it generates in the vowels to, or, or the presence of the umlaut. In our language the umlaut is applied only in the u to indicate that it is pronounced when it is preded by a soft g and followed by an i or an e . The a , o , u umlaut ( s , s , ) are pronounced as the diptongo ae of Latin, French oe and French respectively.
