A number of noted scholars from Jacob Grimm to Streitberg have treated this topic. The latter in his Gotisches Elementarbuch (1920) summarizes, under the corresponding heads of the syntactical part of his grammar, the results of the various investigators. I intend in this paper to make an annotation here and there to their statements. And since I have noticed that some critics waver as to where to draw the exact demarcation line, I shall start with a definition of the matter under present consideration, following in part Grimm's Deutsche Grammatik.
