German Plural Nouns With no End Changes

Most nouns in this group are either neuter or masculine and usually contain one of the following endings: -chen, -lein, -el, -en or -er. Nouns in this group do not change their word endings in the plural. There may also be some umlaut changes.

For example:

der Onkel (uncle, singular) ---> die Onkel (plural)

Ich habe nur einen Onkel. (I have only one uncle.)

Ich habe vier Onkel.

The only time a plural ending is added, is during the dative. In this case, the noun always adds an -n ending. See chart below for a summary of this plural group in all cases.
