't kofschip: choosing t or d

If the stem of a regular verb (its ik form, like werk or woon) ends in one of the consonants of 't kofschip (t, k, f, s, ch, p, and also x), the past forms take -t and -te: gewerkt, werkte. Otherwise they take -d and -de: gewoond, woonde. For verbs like leven and reizen, check the infinitive (the dictionary form) instead of the stem.

The pattern

If the stem ends in a consonant from 't kofschip, use -t in the past participle and -te in the simple past; otherwise use -d and -de. If the stem ends in f or s, check the infinitive first: a v or z there means -d and -de.

  • Past participle (the "worked" in "I have worked"): usually ge- + stem + -t or -d, so gewerkt, gewoond (regular participles).
  • Simple past (the "worked" in "I worked yesterday"): stem + -te or -de, plus -n in the plural: werkte, werkten, woonde, woonden (more on the simple past).
  • leven (stem leef) and reizen (stem reis): v and z are not in 't kofschip, so leefde, geleefd, reisde, gereisd.
  • A stem that already ends in t or d gets no extra letter in the participle (gewacht, geantwoord), but the full ending in the simple past (wachtte, antwoordde).
  • Mixed verbs like bakken (bakte, gebakken) and irregular verbs have their own participles, and a few English loanwords follow the sound: skypen, skypete, geskypet.

Why it works this way

The consonants on board are all voiceless: you make them without a buzz in your throat. Put two fingers on your throat and say a long s, then a long z. Only the z buzzes. A voiceless t slides easily after a voiceless sound (werkte, fietste), while a buzzing d fits after a vowel or a buzzing consonant (woonde, belde). The x joins the crew because it is really k plus s: faxen gives faxte and gefaxt.

That explains leven and reizen too. Their v and z are the buzzing partners of f and s, but Dutch spelling usually writes f and s at the end of a word (v and f, z and s), so the stems look like leef and reis. The ending follows the infinitive.

Your ear won't always help. A final d sounds like t (why that happens), so gewoond sounds just like the wrong gewoont. For g, go by the letter, not the accent: many people in the Netherlands say it like ch, yet leggen gives legde and gelegd.

Remember: a kof is a real type of old Dutch sailing ship. Its consonants travel with -t; v and z are not on board, so they travel with -d, even when spelling dresses them up as f and s.

Watch out

  • نادرستIk werkde tot zes uur.

    درستIk werkte tot zes uur.

    werk ends in k; the English -ed is no guide here

  • نادرستWe hebben in Leiden gewoont.

    درستWe hebben in Leiden gewoond.

    n is not on the ship; German speakers often write -t out of habit

  • نادرستEmma wachte op de bus.

    درستEmma wachtte op de bus.

    stem wacht plus -te gives two t's

  • نادرستOpa leefte heel gezond.

    درستOpa leefde heel gezond.

    the infinitive leven has a v

  • نادرستIk heb veel gereist.

    درستIk heb veel gereisd.

    the infinitive reizen has a z

Use it today

Tonight, write three sentences about your day with regular verbs such as werken, fietsen, koken or bellen, for example Ik heb soep gekookt. Before you write each ending, find the stem and ask yourself: is that letter on the ship?

پرسش‌های زبان‌آموزان

What does 't kofschip mean in Dutch grammar?

't kofschip is a memory word for the consonants t, k, f, s, ch and p, plus x. If the stem of a regular verb ends in one of them, the past forms end in -t and -te, as in gewerkt and werkte; otherwise they usually end in -d and -de. Verbs with v or z in the infinitive, like leven and reizen, take -d and -de.

Is it gereisd or gereist?

It is gereisd. The stem reis ends in s, but the infinitive reizen has a z, which is not in 't kofschip, so you write gereisd and reisde.

When do you use -te or -de in the Dutch past tense?

Use -te when the stem of a regular verb ends in t, k, f, s, ch, p or x (werkte, fietste) and -de after other letters (woonde, belde). For stems ending in f or s, check the infinitive: leven and reizen give leefde and reisde.
