"For the first time in the history of RRG, the framework is shown to be a powerful tool also in the realm of diachronic linguistics. Thus, it is to be expected that this book will trigger a new wave of diachronically minded in-depth studies for which RRG serves as the frame of reference. Accordingly, some of the papers demonstrate convincingly that RRG has substantial things to say when it comes to analyzing data from extinct languages or older stages of languages. Moreover, the many thought-provoking ideas expressed in this edited volume suggest that RRG and grammaticalization theory can work hand in hand successfully."Prof. Thomas Stolz, University of Bremen
