Spelling Changes in Plurals

Level 1

When you add the plural ending -en, the spelling of the word often changes to preserve the original vowel sound (long or short).

How It Works

In Dutch, spelling changes to preserve the sound of the singular word when adding plural endings. All plural nouns use the article de.

1. Vowel Rules (a, e, o, u)
Dutch vowels are long in open syllables. When a single vowel letter represents a long sound in an open syllable, it is written once. The letter 'i' is an exception to the dropping rule: a long sound is written ie and stays ie (fiets → fietsen), while a short i still doubles the consonant (bil → billen).
• Short Vowels: To keep a vowel short, double the consonant: man → mannen.
• Long Vowels: To keep a vowel long, drop the extra vowel letter in an open syllable: maan → manen.

2. F/V and S/Z Shifts
If a word ends in -f or -s preceded by a long vowel or diphthong, they often change to -v or -z: brief → brieven, huis → huizen. This shift does not happen after short vowels (e.g., straf → straffen) or if another consonant precedes the f/s (e.g., mens → mensen). Note: Many loanwords ending in -f (like filosoof or fotograaf) keep the -f in the plural, though they still follow the vowel dropping rule: filosofen, fotografen.

3. Other Plural Endings
• -s: Used for words ending in unstressed -el, -er, -en: tafel → tafels.
• -'s: Used for words ending in long pure vowels (a, o, u, i, y) to keep them long: foto → foto's. Exception: Words ending in an accented vowel do not use an apostrophe: café → cafés. Words like zee → zeeën use a trema to indicate a new syllable.

4. Irregular Vowels
Some common words change their vowel sound entirely in the plural: stad (city) → steden, schip (ship) → schepen.

Examples (5)

  1. De mannen werken in de tuin.

    The men are working in the garden.

    Word by Word: The men work in the garden.

    Singular 'man' has a short vowel. We double the 'n' in 'mannen' to keep that vowel short.

  2. Ik zie de manen van Jupiter.

    I see the moons of Jupiter.

    Word by Word: I see the moons of Jupiter.

    Singular 'maan' has a long vowel. We drop one 'a' in 'manen' because a single 'a' in an open syllable is already long.

  3. Zij schrijft drie brieven.

    She is writing three letters.

    Word by Word: She writes three letters.

    Singular 'brief' ends in 'f', which changes to 'v' in the plural 'brieven'.

  4. De bussen komen te laat.

    The buses are coming late.

    Word by Word: The buses come too late.

    Singular 'bus' has a short vowel. We double the 's' to 'bussen' to preserve the short 'u' sound.

  5. Er liggen twee kazen op de tafel.

    There are two cheeses on the table.

    Word by Word: There lie two cheeses on the table.

    Singular 'kaas' (long vowel + s) changes to 'kazen' (one 'a' dropped, 's' becomes 'z').

Common Mistakes

  • Keeping double vowels in the plural.

    maanen
    manen

    In the plural 'ma-nen', the first syllable is open, so a single 'a' is already pronounced long. The second 'a' is redundant.

  • Writing 'manen' (moons) when you mean 'mannen' (men).

    Different Meaningmanen
    mannen

    To keep the 'a' short in 'mannen', you must double the 'n'. Without it, 'manen' is pronounced with a long 'a' and means 'moons'.

  • Using 'het' for plural nouns.

    het huizen
    de huizen

    Even if a word is a het-word in the singular, all plural nouns in Dutch use the definite article de.

Learn This First

To learn plural spelling changes, you first need to understand the basic '-en' plural suffix. More importantly, you must understand Dutch syllable structure (open vs. closed) and general spelling rules, as these dictate whether you need to drop a vowel (maan -> manen) or double a consonant (man -> mannen) to preserve the original vowel sound.
