Modal Verbs: Overview

Modal verbs are the small set of helper verbs that color an action with ability, permission, obligation, desire, or futurity — the verbs behind English "can," "may," "must," "want," and "shall." Dutch has six of them, and learning their shared pattern unlocks an enormous amount of natural speech: once you can say Ik kan..., Ik mag..., Ik moet..., Ik wil..., you can frame almost any action the way a native speaker would. This page is the hub. It introduces all six, shows the one construction they have in common — modal + bare infinitive, with the infinitive pushed to the end — and routes you to a dedicated page for each. It also sends you early to the one feature English speakers reliably get wrong: what modals do in the perfect tense.

The six modals at a glance

Each modal gets one sentence here so you can hear it in action; the dedicated pages drill the conjugations and the fine distinctions.

That last example flags an exception worth pinning now: hoeven is the one "modal" that takes te before its infinitive (hoeft niet te wachten). Every other modal takes a bare infinitive. Hoeven sits on the boundary between true modals and ordinary verbs — see verbs/modals/moeten-and-hoeven.

The shared pattern: modal + bare infinitive at the end

This is the engine of the whole group. A modal verb combines with a bare infinitive — the verb in its dictionary form, with no te in front of it — and that infinitive is pushed to the very end of the clause. The modal itself sits in the normal finite-verb slot (second in a main clause); the infinitive closes the verb bracket (see word-order/verb-bracket).

The contrast with English is sharp. English keeps the modal and the verb adjacent ("I want to go to the market tomorrow"), and it inserts "to" with "want." Dutch does neither: it strips the te and separates the two verbs, parking the infinitive at the clause's right edge with everything else in between. The longer the sentence, the wider the gap — but the infinitive always waits at the end.

The modals are themselves irregular

Don't expect tidy conjugations — the modals are among the most irregular verbs in Dutch, especially in the singular, where they often drop the expected -t. Here are the present-tense singulars side by side; the plural is regular (just the infinitive: kunnen, mogen, moeten, willen).

Notice the missing -t in ik kan, hij mag, zij wil — where a regular verb would have it (hij werkt). Notice too the variation in jij: jij kunt and jij kan both occur, as do jij wilt and jij wil, jij zult and jij zal (the -t forms read as slightly more formal). The kunnen page covers this variation in full, including the inversion forms kun je / kan je.

The big one: modals in the perfect

This is the modal feature English speakers most often get wrong, so the overview routes you to it now, before you build bad habits. When a modal appears in the perfect tense (with hebben), it does not turn into a past participle. Instead, Dutch uses the infinitive of the modal alongside the main verb's infinitive — two infinitives in a row at the end. Grammarians call this the double infinitive or IPP (Infinitivus pro Participio, "infinitive for participle").

So Ik heb het niet *kunnen doen — never Ik heb het niet **gekund doen. The participles *gekund, gemoeten, gemogen, gewild do exist, but only when the modal stands alone, without a following main verb (Ik heb het altijd al gewild, "I've always wanted it"). The moment a main-verb infinitive joins it, the modal reverts to its own infinitive form. This is genuinely tricky and entirely unlike English — give it the dedicated treatment at verbs/modals/double-infinitive-ipp.

Modals as a politeness tool

Beyond their literal meanings, the modals are the backbone of polite Dutch. Kun je...? and Wil je...? turn commands into requests; Zou je...? (the conditional of zullen) makes them more deferential still; Mag ik...? asks permission gracefully. This is why the imperative-alternatives page leans so heavily on them — see verbs/imperative/alternatives. Master the six modals and you've also learned how to be polite in Dutch.

Common Mistakes

Key Takeaways

• The six modals: kunnen (can), mogen (may), moeten (must), willen (want), zullen (shall/will), hoeven (needn't, with negation).
• All take a bare infinitive — no te — and push it to the end of the clause (Ik kan zwemmen). Exception: hoeven takes te.
• The modals are irregular, especially in the singular: ik kan, hij mag, zij wil, with -t often dropping.
• In the perfect, a modal + main verb gives a double infinitive (IPP): heb kunnen doen, not heb gekund. This is the classic English-speaker error.
• Modals are also the core of polite requests: Kun je...?, Mag ik...?, Zou je...?.
