Tis chapter focuses on a rather neglected type of morphological change, that is, the change from derivation to inflection. Contrary to the assumption that derivational patterns usually do not develop any further, this analysis proposes that some derivational constructions may change by acquiring a more functional status, which is characteristic of inflectional categories. Based on the distinction between contentful and procedural constructions, as proposed by Traugott & Trousdale (2013), the emergence of the new constructions can be conceived of as a gradual shif on the contentful-procedural gradient. Te argumentation is based on examination of the -idz(o) constructions in Griko, a Greek-based dialect spoken in South Italy.
