The lexicon accompanying my online Hellenistic Greek Grammar is limited in certain ways because of its purpose. Here’s what I have to say in the introduction to the lexicon:
This brief lexicon is designed to accompany my Introduction to Hellenistic Greek course. It is not intended as a complete dictionary. It does not offer definitions of the Greek words, for example. Instead, it offers example translations, comments on English words derived from a given Greek word, and occasional comments on usage. For serious study of specific Greek texts, you should invest in a more complete lexicon.
The numbers on the left indicate the number of times the accompanying word appears in the Greek New Testament. The numbers on the right indicate the lesson(s) in whose vocabulary list the word appears in this course.
For each word, I give a variety of English glosses (translation hints) that correlate loosely with the variety of meanings that would need to be defined in a more complete work. It is my goal to one day add such definitions, but I simply don’t have the time right now. Perhaps I’ll get started on that next Summer.
