Welcome to lesson three of the A2 Dutch Grammar Course. In this lesson you are going to expand your knowledge of Dutch adjective inflection. In the A1 course you learned the basic rule: adjectives before a noun usually get an -e ending, but there is one important exception — when the noun is a het-word used with the indefinite article een. In this lesson you are going to look at three things that build on that foundation. First, you will learn the spelling rules that apply when you add -e to an adjective. Second, you will see how adjectives behave after demonstrative pronouns such as deze, die, dit, and dat. Third, you will learn about a special group of adjectives called stofnamen — material adjectives — which are formed differently from all other adjectives.

De basisregel — kort overzicht

Let's start with a quick overview of the inflection table — you know this from A1. Adjectives before a noun almost always get an -e ending. The single exception is when you use an adjective with een before a het-word. So: de mooie fiets — with -e. Het mooie huis — with -e. Een mooie fiets — with -e, because fiets is a de-word. But een mooi huis — no -e, because huis is a het-word after een. In the plural, adjectives always get -e regardless of gender. This is the foundation. In this lesson we are going to look at the spelling changes that happen when you add that -e, and at two special situations: adjectives after demonstrative pronouns, and material adjectives.

Spellingregels bij de -e uitgang

When you add -e to an adjective, four spelling situations can apply. The first is the short vowel rule. When the adjective has a short vowel followed by a single consonant, you double that consonant before -e. Dik becomes dikke. Wit becomes witte. This is the same rule you know from verb conjugation. The second rule applies when the adjective has a long vowel written as two vowels. The double vowel becomes single before -e, because the syllable opening already keeps the vowel long. Groot becomes grote — one o, not two. Laag becomes lage. Rood becomes rode. The third rule concerns the letters f and s. When an adjective ends in f or s with a long vowel sound, the f changes to v and the s changes to z: lief becomes lieve, grijs becomes grijze. But if the word has a short vowel, the consonant doubles instead — laf becomes laffe, and fris becomes frisse. The fourth category stays unchanged. Diphthongs like nieuw simply add -e to become nieuwe. Endings like -ig and -isch add -e unchanged: rustig becomes rustige, typisch becomes typische.

Aanwijzende voornaamwoorden + bijvoeglijk naamwoord

Demonstrative pronouns take the place of the article. Deze and die are used with de-words: deze fiets — this bike, die fiets — that bike. Dit and dat are used with het-words: dit huis — this house, dat huis — that house. Now the important grammar rule: when an adjective follows a demonstrative pronoun, it always gets -e — for both de-words and het-words. This is different from the een-rule. With een before a het-word, the adjective has no -e: een oud boek. But with dit or dat before the same het-word, the adjective always has -e: dit oude boek, dat mooie huis. Demonstrative pronouns behave like the definite article — they always trigger the -e ending. There is no exception for het-words here.

Bijvoeglijk naamwoord zonder lidwoord

Some nouns, especially uncountable nouns like water, geld, and koffie, often appear without an article. When an adjective comes before such a noun with no article, the same rule applies as with een: whether you add -e depends on the article of the noun. Koffie is a de-word, so you say zwarte koffie — with -e. Geld is a het-word, so you say zwart geld — no -e. Compare: koude soep — soep is a de-word. Koud water — water is a het-word. The pattern is consistent: if you would say een + het-word and omit the -e, you also omit the -e when there is no article at all before a het-word.

Stofnamen — bijvoeglijk naamwoorden op -en

There is a special group of adjectives in Dutch that describe what something is made of. These are called stofnamen. Many common material adjectives are formed by adding -en to the name of the material. Hout — wood — becomes houten. Goud — gold — becomes gouden. Wol — wool — becomes wollen. The standard spelling rules apply to this formation as well: karton becomes kartonnen with a double n, because the vowel before the n is short. Fluweel becomes fluwelen with a single l, because the double vowel becomes single before a new syllable. Now here is the most important rule about these adjectives: they never add an extra -e. You say een houten tafel and de houten tafel — the same form in both cases. This is an exception to the normal inflection rule. In everyday Dutch you will encounter these adjectives constantly — especially in descriptions of furniture, clothing, and materials.

Wat heb je geleerd?

Let's review what you have learned. First: the spelling rules for adding -e. Double the consonant after a short vowel — dikke. Drop one vowel when the double vowel becomes single — grote. And remember the f to v and s to z changes — lieve, grijze. Second: demonstrative pronouns always trigger -e on the adjective — even dit and dat before het-words. So dit mooie huis — always with -e. Third: when no article comes before an uncountable noun, apply the een-rule. De-words still get -e — zwarte koffie. Het-words do not — zwart geld. Fourth: material adjectives are formed by adding -en to the material noun — houten, gouden, wollen. These adjectives never take an extra -e in any context.
