Introduction

Irregular verbs in Dutch don't follow the standard patterns of conjugation that regular verbs do. This means their forms can change in unpredictable ways, especially in the past tense and past participle. Here are the key points:

Present Tense: Some irregular verbs might have changes in the stem vowel in the present tense, especially in the second and third person singular.

Past Tense: Irregular verbs often change their stem vowels in the past tense, and these changes don't follow a predictable pattern. For example, "vinden" (to find) becomes "vond" in the past tense.

Past Participle: The past participle of irregular verbs can also have unexpected forms, often with different prefixes or stem vowel changes. For instance, the past participle of "vinden" is "gevonden".

Because of these variations, irregular verbs in Dutch need to be memorized individually. Examples include "zijn" (to be), "hebben" (to have), "gaan" (to go), among others.
