Systemic polyfunctionality and morphology–syntax interdependencies

, 2017
Abstract The chapter examines classes of grammatical markers that can serve more than one function, polyfunctional markers, spoiling the one-to-one form and function relation which is what morphology tends to do. There are areas of the grammar more prone to this behaviour suggesting that there may be at work principles of morphological ...
