In Dutch grammar, the Simple Past (imperfect) is used to express past events, while the Past Perfect (voltooid verleden tijd) typically expresses an action completed before another action in the past. The Simple Past is formed by conjugating the verb according to its irregular or regular pattern, while the Past Perfect is formed by combining the past participle with the auxiliary verb “hebben” or “zijn” in the Simple Past form.
