COMP trace effects across North Germanic varieties

Different varieties of North Germanic allow a left peripheral element to immediately precede the trace of an embedded wh-subject that has been moved to the matrix left periphery. Across North Germanic we find varieties that allow the insertion of the declarative complementizer at, i.e. similar to English that, but there are also varieties in which we encounter relative markers instead. In varieties of Norwegian the complementizer som may precede the trace of the wh-subject. Faroese is another case, where a group of speakers allows the insertion of the relative marker ið. Danish and Western Jutlandic represent yet another case in that the item der/dæ ‘there’, an element which is otherwise used as a marker of subject relatives as well as functioning as an expletive, also may appear in the corresponding structure.
