How to form the Dutch past participle (ge- ... -d/-t)

The past participle (in Dutch, the voltooid deelwoord) is the fixed verb form used to build the perfect tenses: gewerkt in Ik heb gewerkt (I have worked). It never changes to agree with the subject. For most verbs you build it with one pattern.

Put ge- in front of the stem (the verb without its -en ending) and add -t or -d at the end: ge- + stem + -t/-d. The choice between -t and -d is the same as in the simple past.

1. Find the stem: remove -en from the infinitive. werken → werk, luisteren → luister.
2. Add ge- at the front.
3. Choose the ending with 't kofschip: if the stem ends in t, k, f, s, ch or p, add -t; otherwise add -d. werk → gewerkt, luister → geluisterd.

You never write two of the same consonant at the end of a participle. A stem that already ends in t or d therefore keeps its single letter, with nothing added: praten → gepraat (talked), melden → gemeld (reported).

Verbs that begin with the unstressed prefixes be-, er-, ge-, her-, ont- or ver- take no ge-. The prefix takes its place; you still add -t or -d.

• betalen (to pay) → betaald
• vertellen (to tell) → verteld
• ontmoeten (to meet) → ontmoet (stem ontmoet already ends in t)
• herhalen (to repeat) → herhaald
• gebeuren (to happen) → gebeurd

Verbs ending in -eren are not in this group: they keep ge- like any regular verb, and because the stem ends in r they take -d: studeren → gestudeerd (studied), feliciteren → gefeliciteerd (congratulated).

A group of common verbs — the strong verbs — build the participle differently: they keep ge- but end in -en, and they often change the stem vowel. These you learn one at a time.

• lopen (to walk) → gelopen
• lezen (to read) → gelezen
• schrijven (to write) → geschreven
• nemen (to take) → genomen

The past participle is not a tense on its own; it is a building block for other forms, always with the same shape:

• In the present perfect: Ik heb gewerkt. (I have worked.)
• In the pluperfect: Ik had gewerkt. (I had worked.)
• As an adjective before a noun: een gebakken ei (a fried egg).

The most common error is adding ge- to a prefix verb: it is betaald, not gebetaald; verteld, not geverteld. The prefix already does the job of ge-. A second trap is the ending: follow 't kofschip, so fietsen gives gefietst with -t (the stem fiets ends in s), not gefietsd.
