[Lingtyp] Tag Question Constructions

[Scott T. Shell]

Hello everyone,

I am currently researching the construction of tag questions and the phenomena of auxiliary copying. Does anyone know if the languages listed below cannot reduplicate the auxiliary verb? If they cannot, would you please be so kind to provide an ungrammatical example where the operation simply won't work? I am looking to model something like this:

German:
*Hans ist nach Hause gegangen, ist er nicht?
Hans went home, did he not?

Danish 
Scottish Gaelic
Swedish
Welsh
Finnish
Saami (Western and/or Eastern)
Icelandic

Thank you all so much, and have a great day!

Kind regards,
--
