For someone knowing (High) German, pluralizing is a fairly predictable process, with some exceptions: the '''-en''' ending covers pretty much the same words in both languages; the '''-a''' ending is the equivalent for the German '''-er''' plural, where German has [[Germanic umlaut|Umlaut]], Plautdietsch will have vowel fronting in most cases. The '''-s''' and '''-sch''' groups are made almost entirely of polysyllabic nouns which in German have no plural ending.

The most problematic words are those with an '''-e''' plural ending in German. Although the entire class with no ending is made out of them, many other words are treated differently. For example, the plurals for '''Stool''' and '''Stock''' (chair and stick) are '''Steela''' and '''Stakja''' (compare German Stuhl, Stühle; Stock, Stöcke). Since they have their vowels fronted there seems to be no reason for the '''-a''' ending. Many others have been moved into the '''-en''' class: '''Jeboot, Jebooten''' (commandment/s, German: Gebot, Gebote). With some not so common words, there is no certainty about the correct plural, different speakers create them in different ways: the plural of '''Jesaz''' (law) could be '''Jesaza''' or '''Jesazen''' (German: Gesetz, Gesetze).
