Amazon asked me to review a book or two I’ve purchased since all 9 of my reviews got ratings from other buyers that they had helped them decide, so I picked Middle Voice. Here ‘tis.
Not for those who do not have a pretty deep experience studying the grammar of a lot of different languages. BUT, if you do have that background and are fascinated by ergative constructions and the like, this is the book for you. It takes you deep into the intricacies of issues like I cut the bread easily vs The bread cuts easily. If the question of how cut goes from transitive to intransitive (to use sophomore English grammar terminology) intrigues you (hint: it’s Middle Voice), then buy this book.
