träumten

träumten is the past participle of the German verb träumen, which translates to "to dream." As a past participle, träumten is used in German to form perfect tenses and passive voice constructions. When used with the auxiliary verb haben, it forms the perfect tense, indicating an action that was completed in the past. For example, "Ich habe von einer Reise geträumt" translates to "I have dreamed of a journey." In this construction, träumten acts as the past participle of the infinitive verb träumen.

The word träumten itself is the plural past participle form. This means it would be used when referring to multiple subjects having dreamed. For instance, if two or more people dreamed of something, one might say, "Sie träumten von einer besseren Zukunft," meaning "They dreamed of a better future." The singular past participle form is geträumt. The usage of träumten, like other German past participles, depends on the grammatical context and the subject(s) of the sentence. It carries the meaning of a past dreaming experience.
