In 14 contributions, 30 seasoned and novice researchers of linguistics and L2 learning and teaching pay tribute to Marjolijn Verspoor?s scholarship. The umbrella provided by the Dynamic Usage-Based (DUB) account of L2 acquisition appears to be much wider than I had thought. DUB clearly is alive (and kicking). Warmly recommended.

This volume effectively illustrates how Complex Dynamic Systems Theory (CDST) helps us construct an empirically grounded, ecologically realistic understanding of second language learning, with each chapter exploring a different dimension of the approach. Together, these studies provide us with a real feast of ideas and data, all in support of this new perspective.
