Noun Plurals

die Fens___, the gap sits right there, and at first glance the German plural looks like a pile of exceptions: sometimes -e, sometimes -er, sometimes nothing at all. Look closer, though: das Fenster already ends in -er, so the gap simply gives back the rest of the singular (ter), no new plural ending needed. That is not a lucky guess, it is one of only five signals that explain almost the whole German plural system.

Plural endings belong to the biggest single gap family in the C-test, inflectional endings, which make up roughly a fifth of all gaps. German has only five plural patterns, and the gender of the singular almost always tells you which one applies. Look at the article of the base word (der, die, das) and at the ending of the singular: these two signals lead you to the right plural ending. In this chapter we walk through each pattern slowly, with a table, umlaut notes, and a short exercise right after.

Quick rule: Five patterns: -e (often +umlaut), -er (+umlaut), -(e)n (feminine nouns!), -s (loanwords), zero ending (-er/-el/-en). Feminine nouns ending in -e → almost always -n.

The Five Plural Patterns at a Glance

Before the detail, here is the map. Above all, memorise the "common with" column, because gender is your strongest clue:

Keep the rough rule of thumb in mind: feminine → mostly -(e)n. Masculine → mostly -e. Neuter one-syllable → often -er. The other two patterns (-s and zero ending) you recognise from the word form, not the gender.

Fill in the plural form for each noun:

Pattern 1: Ending -e (often with umlaut)

Very many one-syllable masculines form the plural with -e. If the stem has an a, o, or u, an umlaut often comes along (a → ä, o → ö, u → ü). A small group of one-syllable feminines belongs here too, then almost always with an umlaut.

So when a der word or a one-syllable masculine turns up in the C-test, -e is your first guess, and quickly check whether the stem vowel can take an umlaut.

Let us test it: in the first word the ending is the gap, in the second the umlaut is. der Tag has no umlaut here, der Stuhl does.

Pattern 2: Ending -(e)n (no umlaut)

This is the friendliest pattern: feminines almost always take -(e)n and never an umlaut. Whether it is -n or -en depends only on the ending of the singular.

In short: if the word ends in -e, -el, or -er, a single -n is enough. If it ends in -ung, -heit, -keit, -schaft, -ion, or -tät, you add -en. And -in becomes -innen, with a doubled n.

Try it: both words are feminine, so no umlaut, only the ending is missing.

Pattern 3: Ending -er (almost always with umlaut)

Many one-syllable neuters form the plural with -er, and if the stem vowel can take an umlaut (a, o, u, au), the umlaut happens here almost automatically. A small group of masculines follows the same pattern.

Rule of thumb: if you see a short neuter with a, o, u, or au in the stem, guess -er with umlaut. Without an umlaut-capable vowel (like Kind, Bild) it simply stays -er.

Now you: first word the ending, second word the umlaut.

Pattern 4: Ending -s (loanwords)

The -s is the "foreigner pattern": it appears with many loanwords (especially from English and French) and with nouns ending in a full vowel (-a, -i, -o, -u, but not -e). An umlaut never appears here.

If the word "does not look German" or ends in -a, -i, -o, -u, then -s is almost always right. Note: words ending in -e do not belong here, they take -(e)n (Pattern 2).

Two loanwords to practise, both with the same plain ending:

Pattern 5: Zero ending (sometimes with umlaut)

Masculines and neuters that already end in -en, -er, or -el get no new ending. The plural then looks exactly like the singular; only the article changes to die. Some of these words add an umlaut, and that umlaut is then your only signal. The diminutive forms in -chen and -lein also stay endingless.

Remember: if a masculine or neuter ends in -en, -er, -el, no ending is added. All you check is whether the stem vowel a, o, u takes an umlaut. The feminines Mutter and Tochter are the famous exceptions that pluralise with a pure umlaut despite the "die".

Here the gap is the umlaut itself, because there is no ending:

Umlaut in the Plural

The umlaut is not a plural pattern of its own but an extra signal that can accompany patterns 1, 3 and 5. The overview table already says so: -e (often umlaut), -er (almost always umlaut), zero ending (maybe umlaut). With -(e)n and -s, by contrast, an umlaut never appears. So the umlaut does not reveal the pattern to you, it only comes along with it.

Match each noun to its plural form and note which base pattern is behind each one:

Quick Decision Guide

When a plural ending is missing in the C-test, run through this short list. Usually you have the answer within a few seconds:

1. Is the word feminine (die in the singular)? → almost always -(e)n, never umlaut. Exceptions: die Hand → Hände, die Mutter → Mütter.

2. Is it a one-syllable masculine? → mostly -e, often with umlaut (der Stuhl → Stühle).

3. Is it a one-syllable neuter with a, o, u, au? → often -er with umlaut (das Buch → Bücher), otherwise -e.

4. Does a masculine or neuter end in -en, -er, -el? → zero ending, just check the umlaut.

5. Is it a loanword, or does it end in -a, -i, -o, -u? → -s.

6. Does the word end in -in? → -innen. In -ung, -heit, -keit, -schaft, -ion? → -en.

This list replaces the dull memorising of every single plural. Gender and the word ending almost always hand you the right pattern.

To finish, three mixed cases that revisit every pattern:

The final check before the gender signal runs fully on autopilot.

As soon as you see the article of the singular, you usually already know the pattern, and the apparent chaos turns into a short checklist you run in your head.
