zweifeln — German conjugation
to doubt
Indicative
Present (Präsens) Regular
Präsens is the default present for facts, habits, and near-future plans. German has no continuous aspect in the same way as English, so a single form often covers both “I work” and “I am working” when you add a time adverb or context.
Ich arbeite heute im Homeoffice.

Simple past (Präteritum) Regular
Präteritum is a narrative past, common in print and in northern speech, while southern speakers lean on the perfect in conversation. sein and haben keep their Präteritum even when you otherwise avoid the preterite.

Subjunctive

Other forms
Imperative (Imperativ) Regular

| Pronoun | German |
|---|---|
| du | zweifele |
| ihr | zweifelt |
