This handbook aims at a state-of-the-art overview of both earlier and recent research into older, newer and emerging non-standard varieties (dialects, regiolects, sociolects, ethnolects, substandard varieties), transplanted varieties and daughter languages (mixed languages, creoles) of Dutch. The discussion concerns the theoretical embedding, potential interdisciplinary connections and the methodology of the studies at issue, keeping in mind comparability and generalizability of the findings. It presents general concepts and approaches in the broad domain of Dutch variation linguistics and the main developments in different varieties of Dutch and their offspring abroad. The book counts 47 chapters, written by over 40 scholars from the Netherlands, Flanders, Germany, England, South Africa, Australia, the USA, and Jamaica.
