The loss of inflectional morphology is a diachronic process which has played a major role in shaping our linguistic landscape, but has never been the target of focussed research in the same way that the origin of inflectional morphology has been. We offer here a preliminary typology of the operations involved in inflectional loss, distinguishing three change types: the loss of forms, the loss of features, and loss of both at the same time – that is, the loss of entire paradigm cells. These are illustrated with examples from a typologically, genetically and areally diverse set of languages.
