The Analytical Concordance of the Greek New Testament is a massive two-volume work, most helpful for the in-depth study of New Testament Greek, second only to a computerized grammatical concordance. These two volumes constitute volumes 2 and 3 of Baker's Greek New Testament Library. They are a lexical and a grammatical concordance, respectively, of the text of The Greek New Testament, 3d ed. (United Bible Societies, 1975), together with the grammatical analysis of Barbara and Timothy Friberg in the Analytical Greek New Testament, which was vol. 1 of Bakers Greek New Testament Library (1981).
The first volume, Lexical Focus, is like a regular Greek NT concordance in that its organization is alphabetical by lemmas at the highest level, but beyond that the similarity diminishes. Not only is a grammatical tag assigned to the entry word, but every word in the selection of context reproduced with it has a grammatical tag as well, thus permitting study of the grammatical role of the entry word in its literary context as compared with other uses of the same word in the Greek NT. Furthermore, every morphological variant of each lemma appears in alphabetical order beneath the entry lemma, and every grammatical variant is also noted alphabetically within morphologically identical word groups.
Where there is ambiguity in the text, two or more alternative analyses are provided. Five common postpositive conjunctions (de, men, gar, oun, and te) are subgrouped alphabetically according to the grammatical analysis of the preceding word. Canonical order is followed where alphabetical order of words and grammatical tags still produce groups of like entries. Finally, the total number of entries for each lemma is given, as well as the total number of each morphological variant. Because of the unique grammatical status of questions, a special concordance of questions found in the NT is located at the end of the volume, indexed according to canonical order. An appendix provides a list of variants found in the critical apparatus of the Greek New Testament, given in alphabetical and canonical order. A staggering amount of information is thus available to the student of the Greek NT.
Volume 2, Grammatical Focus, takes a different approach to making a concordance of the Greek NT. It orders the words at the highest level by grammatical tag, beginning with the seven major analytical divisions in the following sequence: adjectives and adverbs, conjunctions, determiners (or definite articles), nouns and pronouns, prepositions, particles, and verbs. The lower levels are respectively ordered alphabetically by individual grammatical tags, alphabetically by the entry word for each grammatical tag, and by canonical order. Where there are complex grammatical tags, they may be found listed under each of the simplest tags of which they are comprised. The number of instances of each successive grammatical tag is given following the last entry of each group.
These two volumes provide the student of the NT with a virtually inexhaustible mass of data.
