This dictionary was created in tandem with the paperback Oxford Grammar of Classical Greek published around the same time and also written by James Morwood. The intended audience for these two books seems to have been British schoolchildren or early undergraduates, who would have been reading only easy prose selections like Xenophon and Herodotus, along with a sampling of Homer. This dictionary turns out to be completely inadequate for Greek drama, even the more popular plays, let alone poetry.
At the end of the dictionary is a list of principal parts for 101 irregular verbs. This chart is identical to that in the Oxford Grammar of Classical Greek. It is a pity that the editors didn’t include the second chart, with even more irregular verbs, from the latter book.
All in all, while this might have been a nice budget choice for students who don’t intend to do more with Greek than introductory courses, any English-speaking student wanting a reference for the long-haul or other literary genres will have no choice but to invest in the Liddell & Scott intermediate dictionary (the “Baby Liddell”) or one of the other dictionaries that aimed to be a successor to that.
