This is the single most important choice in Dutch relative clauses, and it is gloriously simple once you see the rule: use die for de-words and for all plurals, and use dat only for singular het-words. English has no equivalent decision to make — who, which, and that are chosen by meaning (person vs thing), not by the gender of a noun. In Dutch the choice is purely grammatical: it tracks the gender and number of the noun the clause describes. If you already know whether a noun is a de-word or a het-word, you already know which relative pronoun to use. This page makes that reflex automatic and clears up the two mistakes English speakers make most.
The rule in one breath
The relative pronoun agrees with its antecedent — the noun it points back to. There are exactly two outcomes:
| Antecedent | Relative pronoun | Example |
|---|---|---|
| de-word, singular | die | de man die... / de vrouw die... |
| het-word, singular | dat | het boek dat... / het kind dat... |
| any plural (de- or het-origin) | die | de boeken die... / de kinderen die... |
So there are really two questions, asked in order: (1) Is the antecedent plural? If yes → die, full stop. (2) If singular, is it a de-word or a het-word? de → die, het → dat. Because every Dutch plural takes the article de, and because all plurals take die, you can also state it as: die unless the antecedent is a singular het-word.
Die — for de-words
Roughly two-thirds of Dutch nouns are de-words, including every person noun and every plural, so die is by far the more common relative pronoun. The antecedent can be the subject or the object inside the relative clause — die covers both; Dutch does not change form for case here.
De buurman die altijd vroeg opstaat, maait nu al het gras.
The neighbour who always gets up early is already mowing the lawn. 'de buurman' is a de-word → 'die'; here 'die' is the subject of 'opstaat'.
De film die we gisteren zagen, was prachtig.
The film we saw yesterday was beautiful. 'de film' → 'die'; here 'die' is the object of 'zagen'.
Ken je die vrouw die daar staat te wachten?
Do you know that woman standing over there waiting? 'de vrouw' → 'die', as subject of the clause.
Note in the second example that the verb zagen sits at the end of the relative clause — die we gisteren zagen — because the clause is subordinate. The die/dat choice and the verb-final rule always travel together (see Verb-Final Order).
Dat — for singular het-words
When the antecedent is a singular het-word, the relative pronoun is dat. This is the form English speakers under-use, because het-words are the minority and the habit of saying die for everything is strong.
Het huis dat we bijna kochten, staat nog te koop.
The house we almost bought is still for sale. 'het huis' is a het-word → 'dat'.
Het kind dat daar huilt, is mijn neefje.
The child crying over there is my little nephew. 'het kind' → 'dat'.
Het cadeau dat je me gaf, was precies goed.
The present you gave me was exactly right. 'het cadeau' → 'dat'.
Be careful not to confuse this relative dat with the conjunction dat meaning "that" (as in ik weet dat...). They are spelled identically and both send the verb to the end, but the relative dat refers back to a specific het-noun, while the conjunction dat introduces a content clause and refers to nothing.
Plurals: always die, whatever the singular gender
Here is the rule that surprises people. A het-word in the singular takes dat — het boek dat... — but the moment it goes plural, it switches to die, like every other plural. Plurality overrides gender. This is because all Dutch plurals take the article de, and de-antecedents take die.
De boeken die op de plank staan, zijn van mijn opa.
The books on the shelf are my grandfather's. Singular 'het boek' → 'dat', but plural 'de boeken' → 'die'.
De kinderen die buiten spelen, wonen hiernaast.
The children playing outside live next door. Singular 'het kind' → 'dat', but plural 'de kinderen' → 'die'.
De huizen die ze bouwen, zijn heel duur.
The houses they're building are very expensive. 'het huis' → 'dat' in the singular, but 'de huizen' → 'die'.
It's the head noun that decides — not the clause
A persistent confusion: the pronoun agrees with the antecedent (the noun before it), never with the subject or any noun inside the relative clause. In het boek dat ik lees, the dat matches het boek — it has nothing to do with ik. Even if the clause's own subject is a de-word, the pronoun still tracks the head noun.
Het boek dat de leraar aanraadt, is uitverkocht.
The book the teacher recommends is sold out. 'dat' matches 'het boek' (het-word), not 'de leraar' inside the clause.
De stoel die het kind omgooide, is kapot.
The chair the child knocked over is broken. 'die' matches 'de stoel', not the het-word 'het kind' that's the subject inside the clause.
Common Mistakes
❌ Het boek die ik las, was spannend.
Incorrect — 'het boek' is a singular het-word, so it must take 'dat', not 'die'.
✅ Het boek dat ik las, was spannend.
The book I read was exciting.
❌ De man dat naast ons woont, is aardig.
Incorrect — 'de man' is a de-word, so it takes 'die', not 'dat'.
✅ De man die naast ons woont, is aardig.
The man who lives next to us is nice.
❌ De boeken dat op tafel liggen, zijn van mij.
Incorrect — plurals always take 'die', even when the singular ('het boek') is a het-word.
✅ De boeken die op tafel liggen, zijn van mij.
The books on the table are mine.
❌ Het meisje dat de jongens kennen is mijn zus.
The pronoun is correct ('het meisje' → 'dat'), but the verb is misplaced — 'kennen' must end the clause and a comma must close it: 'dat de jongens kennen, is...'.
✅ Het meisje dat de jongens kennen, is mijn zus.
The girl the boys know is my sister.
❌ Het kind die speelt in de tuin, is moe.
Incorrect — 'het kind' is singular het → 'dat', and the verb 'speelt' should end the clause: 'dat in de tuin speelt'.
✅ Het kind dat in de tuin speelt, is moe.
The child playing in the garden is tired.
Key Takeaways
- die = de-words (singular) and all plurals; dat = singular het-words only.
- The pronoun agrees with the antecedent's gender and number, never with the clause's subject.
- Plurality overrides gender: het boek → dat, but de boeken → die. Check "plural?" first.
- The article you learned with the noun is the shortcut: de → die, het (singular) → dat.
- The relative dat (pointing to a het-noun) looks identical to the conjunction dat ("that") — both send the verb to the end, but only the relative one refers to a noun.

- Dutch Relative Clauses: OverviewB1 — How Dutch attaches a who/which/that clause to a noun — the pronoun agrees with the noun's gender and number, and the verb is banished to the end of the clause.
- Wat as a Relative PronounB2 — When Dutch uses wat instead of dat or die — after alles/iets/niets, after a neuter superlative, after dat, and when the antecedent is a whole clause.
- Wie: Relatives for People after a PrepositionB2 — When a relative pronoun referring to a person is governed by a preposition, Dutch uses preposition + wie — met wie, aan wie, op wie — and never waar- or die.
- De vs Het: The Definite ArticleA1 — Dutch has two words for 'the': het for neuter singular nouns only, and de for common-gender singulars and ALL plurals. The choice is fixed per noun and drags the demonstratives (dit/dat vs deze/die) and the adjective ending along with it — including the one place an adjective loses its -e: een mooi huis.
- De-words and Het-words: Noun GenderA1 — Dutch has a two-way gender system: common-gender de-words (about two-thirds of nouns, from the merged old masculine and feminine) and neuter het-words (a closed-ish minority worth memorising). Gender fixes the article, both demonstratives, the relative pronoun and the adjective ending — and the plural article is always de.
- Verb-Final Order in Subordinate ClausesA2 — After a subordinating conjunction, relative pronoun, or question word, the entire verb cluster — including the finite verb — moves to the end of the clause.
