This article presents a constructional analysis of the uses of left-peripheral so in Early New High German. This element is known as a resumptive element, which takes up an adverbial clause and integrates it into a main clause. While this seems a valid analysis for constructions with preposed adverbial clauses, it is not compatible when so is preceded by adverbs or main clauses.
First, a quantitatively informed picture is presented. A network is proposed that centers around a prototype in which so connects a protasis and apodosis when so follows verb-final and verb-initial clauses. Second, it is argued that so following verb-second clauses is loosely connected to this network. Finally, it is considered whether and to what degree the use of so following adverbs should be analyzed in the same way as so following adverbial clauses. It is argued that patterns with adverbs are not in paradigmatic relation with adverbial clauses. Moreover, their function is different, as they are backward-oriented and take up earlier constituents.
