Allusion has been made in the preface to certain peculiarities of New Testament Greek, which distinguish it from the classic Greek of the heathen world.

This Lexicon indicates some of these peculiarities, by distinguishing three classes of words:

I. Later Greek words, marked L. G., the occurrence of which may be regarded as commencing within the Later Greek period, which is here reckoned from and includes the writing of the historian Polybius, B.C. 204-123.

II. New Testament words, marked N. T., which only occur in the New Testament, or if found elsewhere are only in certain peculiar quarters.

III. Septuagint words, marked S., which besides their occurrence in the New Testament are found only in the Septuagint Version of the Old Testament, the Greek Apocryphal books, and kindred writings; and the meaning of which is to be studied, not in the usage of classical Greek writings, but rather in the light of the Hebrew Old Testament, and the writings of Jewish authors who were familiar with Hebrew ideas and Hebrew literature.
