This textbook proceeds from the basic structures of the verb and noun to the more complex constructions. It contains vocabulary lists, grammatical explanations, paradigms, and exercises. Whereas it is expected that the volume will be primarily used in classroom settings, the text was written with the intention that a person, using the Translation Key to evaluate his or her exercises, could readily progress to competent exegetical studies without professorial help.
I've heard that there are many more user/student friendly Greek grammars out there but this happens to be the one I used for 4 of my 6 semesters of Greek. I know it pretty well and it is workmanlike and fair. The author and book should not be judged based on my rusty ability with the Greek text.
