This is the reference grammar that I needed when I was in graduate school! This grammar is completely compatible with Herbert Weir Smyth's GREEK GRAMMAR (Harvard Univ. Press) and that is extremely helpful. What is unique and most praiseworthy about this book is that it gives examples for its syntactical categories, both in Greek and in English. It summarizes the scholarly controversy about verbal aspect and comes to its own conclusions in an even-handed way. This is fine book that I do not hesitate to recommend to my graduate and undergraduate students.
