The subject of this study is verbal word-formation via suffixal derivation in Middle High German. In the framework of a synchronic and functional system analysis it investigates the interaction between the verbalization morpheme -en, understood here as an element in word-formation, and the >explicit< suffixes -igen, -i(e)ren, er(e)n, -enen, -el(e)n, -(e)zen, and -(e)sen. The central concern is the identification of the motivated synchronic relationship of a given verb with its precedent base-form and the assignment of formations describable as motivated to derivation patterns.
