Metzger is a Must!
I have used Metzger?s Lexical Aids since shortly after the third edition appeared in 1969, and have given copies to friends and seminarians. It is useful for non-specialists in the language wishing to prioritize their study time. Perennial favorites are the lists: of words according to frequency, of words according to Greek root, of prepositions used as verbal prefixes, and of the principal parts of selected verbs. The index of words cited becomes more valuable as one uses the work.
This is a lexical (vocabulary) aid, and not a substitute for a foundational textbook in the elements of the language. Those who need to do so should use this with good charts of the Greek grammar close at hand.
Metzger?s work can be used profitably with Kubo?s verse-by-verse Reader?s Greek-English Lexicon of the New Testament, and as preparation for a work such as Trenchard?s Complete Vocabulary Guide to the Greek New Testament.
At the alibris.com price, even the church mice can afford Metzger?s work!
