The Old English Case System. Case and Argument Structure Constructions by Kirsten Middeke is a Construction Grammar account of Old English argument structure that integrates modern cognitive corpus linguistics and traditional philological work. This is the first major study on Old English morphosyntax from a constructional perspective, based on findings from various strands of theoretical linguistics, including generative approaches, constructionist accounts, quantitative linguistics, and many more. It argues for a new take on historical comparative syntax, a field which has been dormant for quite a while but might see a new boost through the ideas presented here.
