The Ultimate Guide to Dutch Relative Pronouns: Wie, Wat, Die, and Dat

Introduction: Why Relative Pronouns Matter in Dutch

Imagine you're describing a book you just finished or a colleague who helped you out. You want to say, "The book that I read last week was incredibly interesting" or "The woman who helped me at the municipality was very friendly." To connect these thoughts naturally, you need one of Dutch grammar's most essential tools: the relative pronoun.

In Dutch, relative pronouns (known as betrekkelijke voornaamwoorden) are the glue that holds complex sentences together. They allow you to add detail, clarify who or what you are talking about, and transition from simple, repetitive sentences to natural, fluent Dutch. However, for many expats, language learners, and those preparing for their civic integration exams (inburgeringsexamen), choosing between wie, wat, die, and dat can feel like a game of grammatical roulette.

If you have ever found yourself pausing mid-sentence, wondering whether to use die or dat, or why wie suddenly turned into waar, you are not alone. This ultimate guide will demystify Dutch relative pronouns, break down the rules with clear examples, explain how relative clauses affect mastering Dutch word order, and give you practical tools to use them with confidence.

The Basics: What is a Relative Pronoun?

Before diving into the Dutch rules, let's quickly look at what a relative pronoun does. A relative pronoun links a subordinate clause (a relative clause) to a main clause. It refers back to a noun or pronoun mentioned earlier in the sentence, which we call the antecedent.

For example:

• De man die daar loopt, is mijn buurman. (The man who is walking there is my neighbor.)
• In this sentence, de man is the antecedent, and die is the relative pronoun referring back to him.

In English, we use "who," "whom," "which," or "that." In Dutch, we primarily use die, dat, wie, and wat. Let's look at how to choose the correct one every single time.

1. When to Use "Die" and "Dat"

The choice between die and dat is the most common decision you will have to make. Fortunately, the rule is highly systematic and relies entirely on grammatical gender and number. If you already know your Dutch articles (de and het), you are halfway there!

Use "Die" for De-Words (Singular) and All Plurals

We use the relative pronoun die when referring back to:

• Singular "de" nouns (both masculine and feminine, representing people, animals, or things).
• All plural nouns (regardless of whether they are de or het nouns in their singular form).

Let's look at some examples:

• De man die daar staat, is de bakker. (The man who is standing there is the baker. - "De man" is a singular de-word.)
• De kat die op de stoel slaapt, is van mij. (The cat that is sleeping on the chair is mine. - "De kat" is a singular de-word.)
• De boeken die op tafel liggen, zijn nieuw. (The books that are lying on the table are new. - "De boeken" is plural.)
• De huizen die daar gebouwd worden, zijn duur. (The houses that are being built there are expensive. - "Het huis" is a het-word, but it is plural here, so we use die.)

Use "Dat" for Het-Words (Singular)

We use the relative pronoun dat when referring back to:

• Singular "het" nouns (neuter nouns representing things, animals, or concepts).

Let's see this in action:

• Het boek dat ik gisteren kocht, is erg spannend. (The book that I bought yesterday is very exciting. - "Het boek" is a singular het-word.)
• Het kind dat in de tuin speelt, is mijn neefje. (The child who is playing in the garden is my nephew. - "Het kind" is a singular het-word.)

If you struggle to remember whether a noun is a de or het word, don't worry. StroopTaal's interactive article mastery games are specifically designed to help you build the muscle memory needed to identify noun genders instantly, making your choice between die and dat completely automatic.

2. When to Use "Wie" and "Wat"

While die and dat are the workhorses of Dutch relative clauses, wie and wat have specific, highly defined roles. Mixing them up is a common mistake for English speakers, who often assume wie behaves exactly like "who."

When to Use "Wie" (Who / Whom)

Unlike in English, you cannot use wie as a direct relative pronoun to refer to a person in a standard relative clause. For example, you cannot say: De man wie daar loopt. You must say: De man die daar loopt.

You only use wie as a relative pronoun in two specific scenarios:

Scenario A: After a Preposition Refering to a Person

When the relative pronoun refers to a person and is preceded by a preposition (like met, voor, aan, over, etc.), you must use wie.

• De collega met wie ik samenwerk, is erg aardig. (The colleague with whom I work is very nice.)
• De vrouw aan wie ik de brief gaf, glimlachte. (The woman to whom I gave the letter smiled.)
• De vrienden over wie ik je vertelde, komen vanavond. (The friends about whom I told you are coming tonight.)

Scenario B: "He who..." / "The person who..." (Without an antecedent)

If the relative pronoun does not refer back to a specific noun in the sentence, but rather means "the person who" or "whoever," we use wie.

• Wie dit leest, is gek. (Whoever reads this is crazy.)
• Wie zijn huiswerk niet maakt, krijgt een laag cijfer. (He who does not do his homework gets a low grade.)

When to Use "Wat" (What / Which)

We use wat as a relative pronoun in four distinct situations:

1. After Indefinite Pronouns

If the antecedent is an indefinite pronoun like alles (everything), iets (something), niets (nothing), veel (much), or weinig (little), you must use wat.

• Dat is alles wat ik weet. (That is everything that I know.)
• Er is iets wat ik je moet vertellen. (There is something that I must tell you.)
• Er is niets wat we kunnen doen. (There is nothing that we can do.)

2. After a Superlative Adjective Used as a Noun

When you are referring back to a superlative construction (the best, the most beautiful, the funniest), you use wat. To understand how these adjectives are formed, check out our guide on comparative and superlative adjectives in Dutch.

• Het leukste wat ik deze week heb gedaan, was naar het park gaan. (The nicest thing [that] I did this week was going to the park.)
• Dat is het mooiste wat ik ooit heb gezien. (That is the most beautiful thing [that] I have ever seen.)

3. Referring to an Entire Sentence

Sometimes, the relative pronoun doesn't refer to a single noun, but to the entire statement that came before it. In English, we use "which" in this context. In Dutch, we use wat.

• Hij kwam veel te laat, wat erg vervelend was voor de rest van de groep. (He arrived much too late, which was very annoying for the rest of the group.)
• Zij heeft haar examen gehaald, wat geweldig nieuws is! (She passed her exam, which is great news!)

4. After Neuter Adjectives Used Abstractly

If you refer back to an abstract neuter adjective (like het belangrijke, het gekke), you use wat.

• Het gekke wat hij zei, herinner ik me nog goed. (The crazy thing [that] he said, I still remember well.)

3. The Tricky Exception: Pronominal Adverbs (Waar + Preposition)

Now that you know how to use prepositions with people (preposition + wie), you might wonder: what about prepositions with things? Can you say het boek over dat ik sprak?

The short answer is: No.

In Dutch grammar, when a relative pronoun refers to a thing (not a person) and is preceded by a preposition, you cannot use die or dat. Instead, you must combine the word waar with the preposition to form a pronominal adverb (voornaamwoordelijk bijwoord).

Let's compare people and things to see how this works:

Notice how the preposition merges with waar. In modern spoken Dutch, these compound words are often split, which is a key aspect of natural word order. For instance, you can say: Het project waar ik aan werk. Practicing this splitting technique is highly recommended for achieving a native-sounding flow.

4. Word Order in Relative Clauses

Relative clauses are always subordinate clauses (bijzinnen). In Dutch, subordinate clauses have a very strict rule: all verbs must go to the very end of the clause.

Let's look at how a simple main clause changes when it becomes a relative clause:

• Main clause: Ik heb gisteren een boek gekocht. (I bought a book yesterday.)
• Relative clause: Het boek dat ik gisteren heb gekocht, is spannend. (The book that I bought yesterday is exciting.)

Notice how the auxiliary verb heb and the past participle gekocht both migrated to the very end of the relative clause. This can be one of the most challenging structures to master when speaking spontaneously. For a deeper dive into how to construct these sentences, explore the rules of Dutch word order.

Summary Cheat Sheet

To help you quickly decide which relative pronoun to use, refer back to this handy summary:

• Die: Use for singular de-words and all plurals.
• Dat: Use for singular het-words.
• Wie: Use for people only after a preposition (e.g., met wie), or when meaning "whoever."
• Wat: Use after alles, iets, niets, veel, weinig, after superlatives, or when referring to an entire preceding sentence.
• Waar + Preposition: Use for things after a preposition (e.g., waarop, waaraan).

How to Practice and Master Relative Pronouns

While understanding the rules of relative pronouns intellectually is an important first step, applying them in real-time conversations requires active practice. Here are some actionable tips to help you build confidence:

1. Identify "De" and "Het" daily: Since choosing between die and dat depends entirely on noun gender, make it a habit to learn the article of every new noun you acquire.
2. Write variations of the same sentence: Take a simple sentence like "The house is beautiful" and expand it using different relative pronouns. (e.g., Het huis dat ik gisteren zag... Het huis waarin ik woon...).
3. Listen for "wat" in native speech: Pay attention to how native Dutch speakers use wat to comment on entire situations (e.g., "Het regent alweer, wat echt jammer is!").
