This document is a preface to an intermediate Greek-English lexicon. It was undertaken to meet the needs expressed by experienced schoolmasters. The lexicon is based on the seventh edition of Liddell and Scott's Greek-English lexicon from 1883. It differs from older abridgments by [1] being based on the most recent edition, [2] containing significantly more content through fuller definitions, forms, and citations of authorities, and [3] including words used by authors up through the New Testament period. The preface provides details on the lexicon's approach to content, forms, derivations, compounds, and citations.
