Dutch modal verbs

Dutch has a small set of modal verbs — kunnen, moeten, mogen, willen and zullen — that express ability, obligation, permission, wish and future. They work like a frame: the modal is conjugated in second position, and the main verb drops to the end of the clause as a bare infinitive. Learn their irregular conjugations and this one word-order rule, and you can build the majority of natural Dutch sentences.

The five modals at a glance

Conjugation tables

Modals are irregular in the singular: the ik and hij forms often share a shape that is not the bare stem. The plural is regular (the infinitive).

Both jij kunt and jij kan are correct; kunt is the traditional standard, kan is very common in speech. Likewise jij wilt and jij wil both occur. The imperfect (past) forms are worth knowing too, because modals are usually used in the imperfect rather than the perfect:

Wou is the colloquial past of willen, fine in speech; wilde is standard in writing. The zou/zouden forms build the conditional — see the future tense.

Word order: the infinitive goes to the end

This is the single most important pattern. In a main clause, the modal takes second position and the lexical verb becomes a bare infinitive at the very end.

Everything else — objects, adverbs, time and place — sits between the modal and the final infinitive. In a subordinate clause both verbs cluster at the end: …omdat ik Nederlands wil leren (…because I want to learn Dutch). This end-cluster behaviour is the core of Dutch word order.

Using the modals precisely

kunnen covers ability and possibility: Kun je zwemmen? (Can you swim?), Dat kan gebeuren (That can happen). moeten is obligation or strong necessity: Ik moet werken (I have to work). It also expresses logical certainty — Hij moet thuis zijn (He must be home). mogen is permission: Je mag hier roken (You're allowed to smoke here), and its past mocht softens requests. willen is wanting: Ik wil koffie (I want coffee) — note it can take a direct object without an infinitive.

Mogen versus kunnen

English "can" blurs ability and permission, which trips learners up. Dutch keeps them separate. Kan ik hier parkeren? asks whether parking is physically possible; Mag ik hier parkeren? asks whether it is allowed. When you mean "am I permitted", use mogen. Similarly, to ask permission politely, Mag ik…? is the natural choice, not Kan ik…?

Hoeven: the negative of moeten

To say something is not necessary, Dutch does not usually negate moeten. It uses the special verb hoeven, which appears almost only with a negation (niet, geen, nooit) and pairs the infinitive with te.

Beware the false friend: Je moet niet komen does not mean "you don't have to come" — it means "you must not come". For "don't have to", always use hoeven. This is one of the most common and consequential errors learners make, listed among the common mistakes Dutch learners make.

The perfect with modals: double infinitive

When a modal appears in the perfect tense together with a main verb, the modal surprisingly takes an infinitive form rather than a participle — the "infinitivus pro participio" or double-infinitive construction: Ik heb niet kunnen komen (I haven't been able to come), Ze heeft moeten werken (She had to work). A modal used alone, however, forms a normal participle: Ik heb het niet gewild (I didn't want it). Most of the time, though, the imperfect (ik kon, ik moest) is simpler and more natural than the perfect. See the perfect tense for the helper rules.

Belgian usage

The forms and rules are shared standard Dutch. In Flemish speech gij kunt/gij moogt appear with the gij pronoun, and moeten niet is sometimes heard colloquially for "don't have to" — but in careful Dutch, north and south alike, hoeven is the correct choice. The word mogen also does heavier duty in Flanders in polite offers (Mag het iets meer zijn? at the counter), which is standard across the language area.
