I have doubts about his honesty.
A feeling of uncertainty or lack of conviction about something.
Ohne Zweifel ist er der beste Kandidat.

Ich zweifle nicht an seinen Fähigkeiten.

Often used with 'an' + accusative (e.g., Zweifel an jemandem/etwas).
A specific instance or reason for feeling uncertain.
Das wirft viele Zweifel auf.
That raises many doubts.
Common in legal or formal contexts (e.g., 'Zweifel an der Richtigkeit der Angaben').
Use 'an' + accusative for doubts about people/things (e.g., 'Zweifel an der Theorie'). For abstract doubts, 'über' + accusative is also possible (e.g., 'Zweifel über die Zukunft').
The phrase 'im Zweifel' means 'if in doubt' or 'if uncertain' (e.g., 'Im Zweifel für den Angeklagten' = 'In dubio pro reo').
From Middle High German *zwīvel*, from Old High German *zwīfal*, from Proto-Germanic *twīfalą* (doubt, uncertainty), related to *zwei* (two) and *fallen* (to fall). The sense of 'two paths' metaphorically evolved into 'uncertainty between options.'
1. 'Zweifel' is always masculine (der Zweifel). 2. In formal writing, 'Zweifel' often appears in phrases like 'kein Zweifel' (no doubt) or 'im Zweifel' (in case of doubt). 3. Avoid confusing with 'Zweifellos' (undoubtedly) or 'zweifeln' (to doubt, verb).
