Category:Dutch weak verbs (-cht)

A small group of Dutch weak verbs form the past tense and the past participle with -cht instead of -t and have developed vowel sound changes through rückumlaut. These thereby resemble strong verbs but historically have been weak.

Note, in particular, that the past participles of strong verbs end with -en whereas the past participles of these verbs do not.

The group is dominated by several core verbs and those derived from them: brengen, kopen, denken, dunken, plegen, roeken and zoeken.

There are two subclasses. Their paradigms are:

Pattern A, for example kopen – kocht – kochten – gekocht

Pattern B, for example brengen – bracht – brachten – gebracht
