This article discusses the emergence of a new conjugation class in Swedish and Norwegian, the so-called 3rd weak conjugation, characterized by a special dental suffix -dde in the preterit. As an increase in allomorphy, this event violates the one:one mapping of function and form. The breach of this morphological principle is caused not by extramorphological (e.g., random phonological) change but by morphological processes, reanalysis, and analogical extension. It is argued that the addition of a new preterit allomorph is functionally motivated in securing distinctive tense exponence.
