A weak verb: if the stem of the infinitive ends in t, k, f, s, ch or p (remember ’t kofschip), the past takes -te and the participle -t, otherwise -de and -d: belde, opgebeld. → Werkte or woonde: the regular imperfect
Every sentence comes from this course’s word lists or grammar topics. The verb form is highlighted, and the line below says which tense and person it is.
Ik bel je vanavond op.I will phone you this evening.
The principle is familiar from English, but the particles are not the same ones. “Ring up” is opbellen (or simply bellen), “do the shopping” is boodschappen doen, “stop” is ophouden or stoppen. And because the English particle can sit right next to the verb (“ring up tomorrow”), people carry that habit over and write Opbel je me morgen? instead of putting the particle at the end.
The forms are calculated from the rules of the language — twice, in two independent ways — and checked against every hand-written form in this course. The example sentences are the course’s own.
