Regular Verbs: The Kofschip Rule

For regular verbs, add -te(n) to the stem if the stem ends in t, k, f, s, ch, or p (remember: "kofschip"). Otherwise, add -de(n).

To form the imperfectum (simple past) of regular verbs, first find the stem of the verb (infinitive minus -en). Then check the last letter of the stem. If it is one of the letters in "t kofschip" (t, k, f, s, ch, p), add -te for singular and -ten for plural. For all other endings, add -de (singular) and -den (plural).

Infinitive	Stem	Last Letter	Singular (ik/jij/hij)	Plural (wij/jullie/zij)
		k (kofschip)
		s (kofschip)
		k (kofschip)
		p (kofschip)
		n (not kofschip)
		f (kofschip)
		s (kofschip)
		r (not kofschip)

Regular imperfectum forms using the kofschip rule. Note: "leven" has stem "leef" (v→f) and "reizen" has stem "reis" (z→s).

Be careful with verbs whose stem ends in -f or -s after a v→f or z→s spelling change. For example: "leven" → stem "leef" → the f IS in kofschip, but because the original spelling has v, you use -de: "leefde". Similarly, "reizen" → stem "reis" → the s IS in kofschip, but the original z means you use -de: "reisde". The rule applies to the original consonant, not the spelling change.

Ik werkte gisteren de hele dag.

I worked the whole day yesterday.

Wij woonden vroeger in Rotterdam.

We used to live in Rotterdam.

Zij fietste elke dag naar school.

She cycled to school every day.

Irregular Verbs in the Imperfectum

Irregular verbs change their vowel (and sometimes the whole stem) in the imperfectum. These forms must be memorized.

Many common Dutch verbs are irregular in the imperfectum. They do not follow the kofschip rule. Instead, the stem vowel changes, and some verbs change completely. The plural form of irregular verbs typically adds -en to the singular past form (but there are exceptions).

Infinitive	Meaning	Singular	Plural

Common irregular verbs in the imperfectum

Ik was gisteren thuis.

Zij hadden geen tijd.

They had no time.

Hij ging naar de winkel.

He went to the store.

Wij kwamen te laat.

We arrived too late.

Zij schreef een brief.

She wrote a letter.

Imperfectum vs. Perfectum

Use the imperfectum for stories, descriptions, and habitual actions in the past. Use the perfectum for recent events and results.

Both the imperfectum and the perfectum describe past events, but they are used differently. The imperfectum is preferred for: narratives and storytelling, descriptions of past situations, habitual or repeated actions in the past, and background information. The perfectum is preferred for: recent or completed actions, results that are still relevant, and conversational past tense.

Toen ik jong was, speelde ik elke dag buiten.

When I was young, I played outside every day.

Imperfectum: habitual past action and background description.

Ik heb vandaag een boek gekocht.

I bought a book today.

Perfectum: recent completed action.

Het regende en het was koud.

It was raining and it was cold.

Imperfectum: description of a past situation.

Heb je de e-mail al gelezen?

Have you already read the email?

Perfectum: asking about a result.

Common Mistakes

✗Ik werkte bij een stem dat eindigde op "k".

✓Ik werkte (not werkde) because the stem "werk" ends in k (kofschip).

Always check the last letter of the stem against "t kofschip" to determine whether to use -te or -de.

✗Wij was in het park.

✓Wij waren in het park.

"Was" is the singular form of "zijn" in the imperfectum. The plural form is "waren".

✗Hij gingte naar huis.

✓Hij ging naar huis.

Irregular verbs do not add -te/-de. They have their own unique past tense forms that must be memorized.

Imperfectum in the Workplace

Workplace Context

Scenario: The imperfectum is commonly used in professional settings to describe past experiences, previous positions, completed projects, and to tell colleagues about what happened.

Ik werkte vroeger bij een ander bedrijf.

I used to work at a different company.

De vergadering duurde twee uur.

The meeting lasted two hours.

De manager gaf een presentatie over de resultaten.

The manager gave a presentation about the results.

Toen ik bij dat bedrijf werkte, reisde ik veel.

When I worked at that company, I traveled a lot.

In written reports and professional narratives, the imperfectum is the standard past tense. In spoken Dutch, especially in informal contexts, people often prefer the perfectum.
