I am looking into verbal auxiliaries used in various languages and I don't know Scandinavian languages. I've got some information, but I'd like to clear up the question . I am wondering if Swedish and Norwegian use the auxiliary ha with all verbs in the active perfect and plusperfect or if there are exceptions. What about å bli ? As far as I know Danish uses as German both auxiliaries have and väre. What are the verbs functionning with väre only and those that admitt either auxiliary ? Please give translations in case of examples Thanks a lot for the information.
