Exceptions in the second declension

In the second declension of nouns there are certain exceptions.

1. Nouns Nachbar, Bauer und Ungar take the ending -n, instead of the ending -en.

2. Nouns like Name or Samen form the genitive singular with the ending -ens.

This rule applies to a group of nouns ending in –e or –en like der Friede(n), der Gedanke(n), der Glaube(n), der Wille(n), der Funke(n).

3. The noun Herr is also an exception.

4. Finally, the noun Herz is the only neuter gender noun of the second declension.
