Past participle: strong and weak verbs

What is a past participle (voltooid deelwoord)?

• The past participle is the form you use in perfectum:
  ik heb gewerkt, ik ben gekomen.
• In Dutch it is usually one word with ge- at the front.
• You combine it with hebben or zijn.

Step 1 – Weak vs strong vs irregular: what is the difference?

• Weak verbs: regular, predictable endings (-d or -t).
  • werken → gewerkt
  • maken → gemaakt
  • reizen → gereisd
• Strong verbs: vowel and/or consonant change, often ending in -en.
  • komen → gekomen
  • kijken → gekeken
  • vinden → gevonden
  • helpen → geholpen
  • denken → gedacht
• Irregular verbs: special forms you must learn as a whole.
  • zijn → geweest
  • hebben → gehad
  • doen → gedaan

Tip: If the participle does not follow the weak pattern (ge- + stem + d/t), treat it as strong/irregular and learn it by heart.

Step 2 – Building weak participles: ge- + stem + -d / -t

For weak verbs the basic pattern is:

• ge- + stem + -d / -t

Key question: do I add -d or -t? That is step 3.

Step 3 – ‘’t kofschip’ or ‘soft ketchup’: choose -d or -t

Look only at the last consonant of the stem (no vowels):

• If it is in 't kofschip (k, f, s, ch, p, t), you write -t.
• If it is not in that list, you write -d.

Typical confusions:

• Do not look at the infinitive ending -en, only at the stem.
• Do not write both: gewerkdt, gereisdt.

Step 4 – Strong verbs: look for vowel and consonant change

Strong participles often look like this:

• ge- + (changed stem) + -en

• There is no single rule for the vowel change.
• Learn frequent strong verbs as a set: infinitive + simple past + past participle.
  • vinden – vond – gevonden
  • kijken – keek – gekeken

Step 5 – Irregular verbs: special shapes

• Some high‑frequency verbs are simply irregular:

These forms do not follow the weak pattern. Treat them as vocabulary items.

Step 6 – When do you use hebben and when zijn?

• Most verbs use hebben in the perfectum.
• You usually use zijn with:

1. Movement / change of place
   • komen → Ik ben om acht uur gekomen.
   • gaan → We zijn naar het museum gegaan.
   • lopen → Ik ben naar het station gelopen.
2. Change of state (become, stay, die, etc.)
   • worden → Hij is boos geworden.
   • blijven → Zij is thuis gebleven.

Practical rule at A2: If the verb means “go from A to B” or “change into something”, try zijn. Otherwise, use hebben.

Step 7 – Quick 4‑step checklist before you write

1. Find the infinitive
   • Example: werken, komen, vinden.
2. Decide the group
   • Does it follow ge- + stem + d/t? → weak.
   • Does the vowel or consonant change and end in -en? → strong.
   • Is it zijn/hebben/doen or another special verb? → irregular.
3. Choose -d or -t (only for weak verbs)
   • Take the stem.
   • Check last consonant.
   • In 't kofschip → add -t; otherwise → add -d.
4. Choose the auxiliary
   • Movement / change → usually zijn.
   • Everything else → usually hebben.

Self‑check: can you already do this?

• Can you look at a new verb and say if it is probably weak or strong?
• Can you form the correct participle for verbs like werken, reizen, plannen without thinking too long?
• Do you know by heart the participles gekomen, gevonden, gedaan, geweest, gehad?
• Can you decide quickly if you need hebben or zijn in a simple sentence about movement or an activity?

If you can answer “yes” to most points, you are ready to focus on speaking practice and using these forms in real conversations.
