Simple past (imperfect): regular verbs with vowel change

Onvoltooid verleden tijd: regelmatige werkwoorden met klankverandering


Spelling verandert in de verleden tijd bij werkwoorden zoals reizen, hoeven, bakken, slagen.

(Spelling changes in the past tense for verbs like reizen, hoeven, bakken, slagen.)

What’s special here: regular verbs, but spelling changes

These verbs are regular in the simple past (OVT): they still take -de/-den or -te/-ten.

But the spelling of the stem changes to keep the pronunciation the same.

Step-by-step: how to make the OVT form

  1. Find the stem: infinitive minus -en.
  2. Choose the ending:
    • -de / -den (most common here)
    • -te / -ten (like bakte)
  3. Apply the spelling rule (sound-friendly spelling): v→f, z→s, long vowel stays long, double consonant reduces.

1) reizen → reisde(n): z becomes s in the stem

Why? Dutch does not like a voiced z at the end of a syllable, so it becomes s in the stem.

Infinitive Stem OVT singular OVT plural
reizen reis (not reiz) reisde reisden
  • ik/jij/hij reisde
  • wij/jullie/zij reisden

Common mistake: reizde (keep the stem spelling as reis).

2) leven → leefde(n): v becomes f in the stem

Why? Dutch often changes v → f at the end of a syllable.

Infinitive Stem OVT singular OVT plural
leven leef (not lev) leefde leefden

Common mistakes: levde (forgot v→f) • leefte (wrong ending).

3) klagen → klaagde(n): keep the long vowel long

Rule: If the stem ends in an open syllable (it ends in a vowel sound), Dutch writes a double vowel to keep it long.

  • kla-gen → stem: klaag (not klag)
  • OVT: klaagde / klaagden

Common mistake: klagde (this would suggest a short vowel).

4) bakken → bakte(n): double consonant becomes single

Rule: If the stem ends with two identical consonants, you write only one before -te/-ten.

  • bak-ken → stem: bak (not bakk)
  • OVT: bakte / bakten

Common mistake: bakkte (too many k’s).

Quick self-check: can you spot what changes?

  • reizen → stem ends with s (z→s) → reisde(n)
  • leven → stem ends with f (v→f) → leefde(n)
  • klagen → long vowel stays long: aaklaagde(n)
  • bakken → double consonant reduces: kk → kbakte(n)

Mini checklist before you answer

  1. Is it singular (ik/jij/hij) or plural (wij/jullie/zij)? → -de vs -den, -te vs -ten
  2. Does the stem need a spelling fix? z→s, v→f, aa stays aa, kk becomes k
  3. Read it out loud: does it still sound like the infinitive?
  1. There are regular verbs that get a sound change in the simple past (OVT) because of the sound-shift rules, but they are still conjugated as regular verbs.
  2. If the stem ends in -s, but the whole verb ends in -zen, then -den is added. For example: reizen→reisde(n).
  3. If the stem ends in -f, but the whole verb ends in -ven, then -den is added. For example: leven→leefde(n).
  4. If there is a consonant at the end of the stem and a vowel at the end of the syllable in the stem, then we change the vowel. For example: klagen→ klaagde.
  5. If the stem ends in two consonants that are the same, remove one. For example: bakken → bakte
 Reizen (to travel)Leven (to live)Klagen (to complain)Bakken (to bake)
ikreisdeleefdeklaagdebakte
jij, jereisdeleefdeklaagdebakte
hij, zij, hetreisdeleefdeklaagdebakte
wij, wereisdenleefdenklaagdenbakten
julliereisdenleefdenklaagdenbakten
zij, zereisdenleefdenklaagdenbakten
