About Koineum

The New Testament was first written in κοινή, the common Greek of the eastern Mediterranean. Koineum takes its name from that word, and its aim from it too: to make the original text easy to open, read, and study, free of charge.

A reader, first

Koineum began as a place to read. All 27 books are presented in a clean, distraction-free reader that keeps the focus on the Greek text. Tap or click any word and a small card shows its parsing, a brief gloss, and its transliteration, then links you on to the full lexicon entry, all without losing your place in the text.

A lexicon for every word

Behind the reader sits a lexicon with an entry for every word in the Greek New Testament. Each entry gathers a definition, the word’s full parsing, the forms it takes across the text, and a concordance of every verse in which it appears. You can read your way into the lexicon a word at a time, or browse it on its own.

The text and its sources

The Greek is the Nestle 1904 edition of the Novum Testamentum Graece, a respected text now in the public domain. Koineum builds on open scholarship throughout: the text and its word-by-word tagging come from the Biblical Humanities project, and the glosses and definitions come from STEPBible, created by Tyndale House in Cambridge, drawing on Abbott-Smith and, where Abbott-Smith is silent, Liddell and Scott. Full credits and licenses are listed on the terms page.

Free, and growing

The reader and the lexicon are complete, and they are free. They will stay free. Beyond them, deeper tools for studying and learning the language are in the works, and as they arrive the reading at the heart of Koineum will remain open to everyone.

Private by default

Reading needs no account, and Koineum sets no tracking cookies and builds no profile of you. You can come, read, and study without signing in or being followed. The privacy page explains exactly what is and is not collected.
