There has been a flood of new Biblical Hebrew grammar textbooks over the past couple of decades, most from the United States, but Weingreen first published in 1939 has stood its own against all of them. The reasons for this are clarity of presentation and a sound pedagogical approach. Explanations are clear and crisp, devoid of excessive verbiage.The book is thorough without being overwhelming and what is particularly important is that the grammar is presented with supporting exercises in lessons that are manageable in size and scope. It is a great pity that Oxford's Clarendon Press has not seen fit to commission an answer key with comments to the exercises, as this would be invaluable to self-learners. However all is not lost because an answer key prepared by a group of users now appears on the internet. If I were allowed to choose only one textbook of Biblical Hebrew then it would be this one and without reservation.
