Does anybody have a full list of german verbs that take akkusativ object? I have found a list fot dative but couldn't found for akkusativ.
I'm not exactly sure why people always ask for full lists of verbs (do you have a full dictionary of German?) ...
One way to get a list is through the dictionary of verb valence, https://grammis.ids-mannheim.de/verbvalenz. Select Kakk (accusative complement) on the left and click "Search". This will give you a list of verbs for which a meaning exists in which the verb can be used with an accusative complement (~ object). (If you check "verbspezifische Suche", it will list each verb only once). By chosing specific sentence structures (Satzbaupläne) on the left, you can further narrow down your results, say, to verbs with a meaning where an accusative complement is required (for that, you would need to go through all entries that include Kakk [where the Kakk is not in parantheses because that indicates optionality]).
The dictionary dictionary of verb valence is not that comprehensive as yet but it may still be a starting point :).
