Glossary

The words that keep coming up when people compare Bible translations, in plain terms. For the bigger questions, see the FAQ.

How translations are made

Formal equivalence (word-for-word): A translation method that stays as close as it can to the exact words and grammar of the Hebrew, Aramaic, and Greek, even when the English comes out a little stiff. The ESV, NASB, LSB, and KJV sit here.
Dynamic equivalence (thought-for-thought): Also called functional equivalence. A method that aims to reproduce the meaning and effect of the original in natural English, rephrasing freely to do it. The NLT, NIV, and CEB lean this way.
Optimal / mediating equivalence: A deliberate middle path — leaning formal or dynamic verse by verse depending on which reads better without losing accuracy. The CSB calls its method “optimal equivalence”; the NET aims for a similar balance.
Translation committee: The group of biblical scholars — usually several dozen, from a range of denominations — who produce a modern translation over years, with drafts reviewed by other scholars and English stylists. It’s why committee translations are trusted for study in a way single-author paraphrases aren’t.
Gender-inclusive language: Rendering a generic masculine term in the original (“brothers,” a generic “he”) with wording that makes the inclusion of women explicit (“brothers and sisters,” “they”) where the original clearly addresses everyone. Translations vary from traditional (keep the masculine form) to moderate to thoroughly inclusive.
Paraphrase: A restatement of an existing English translation in looser, fresher words — usually one author’s phrasing rather than a committee’s. The Living Bible and The Message are the best known. Vivid for reading, but not built from the original languages and not suited to study.

Where the text comes from

The autographs: The original manuscripts of the biblical books, as first written. None survive; every Bible is translated from copies.
Textual criticism: The scholarly work of comparing the surviving handwritten copies to reconstruct the earliest recoverable wording. It’s the reason a modern Bible has footnotes like “some manuscripts read…”.
Manuscript: A hand-written copy of a biblical text or part of one. For the New Testament there are around 5,800 in Greek alone, ranging from small papyrus scraps of the 100s to complete medieval codices.
Textus Receptus: The Greek New Testament text assembled by Erasmus in the 1500s from a few late medieval manuscripts, lightly revised afterward. It stands behind the KJV and NKJV. Part of the broader Byzantine tradition, but not identical to the Majority Text.
Critical Text: Also called the Nestle-Aland or eclectic text. A Greek New Testament reconstructed by weighing every known manuscript, including papyri from the 100s–300s found in the last two centuries. Nearly every modern translation uses it.
Majority Text: A Greek New Testament that follows, at each point, the reading found in the greatest number of surviving manuscripts — most of them Byzantine and medieval. No major English translation is based on it; a few small ones are.
Masoretic Text: The standard Hebrew text of the Old Testament, preserved and standardized by Jewish scribes (the Masoretes) between roughly AD 500 and 1000. Every translation here starts from it.
Septuagint (LXX): A Greek translation of the Hebrew Scriptures made a couple of centuries before Christ. Often what the New Testament authors quote, and it sometimes preserves an older reading than the Masoretic Hebrew.
Dead Sea Scrolls: Hebrew (and some Greek and Aramaic) manuscripts found from 1947 onward in caves near Qumran, on the northwest shore of the Dead Sea. Written between roughly 250 BC and AD 68, they push the Hebrew evidence back about a thousand years and mostly confirm how carefully the text was copied.
Vulgate: Jerome’s Latin translation of the Bible, made around AD 400 and the standard Bible of the Western church for over a thousand years. Wycliffe’s 1382 English Bible was translated from it.

Editions and formats

Study Bible: An edition that adds explanatory notes, cross-references, book introductions, maps, and articles below or beside the text. The notes are a separate work from the translation — the ESV Study Bible and the NIV Study Bible use the same ESV and NIV text as any other edition.
Red-letter edition: An edition that prints the words spoken by Jesus in red. A 20th-century American convention; some translations (the NET, the NRSVue) don’t use it at all.
Interlinear: An edition that prints the Hebrew or Greek with a word-for-word English gloss directly beneath each word, plus a readable translation alongside. A study tool, not a reading Bible.
Lectionary: A schedule of Bible readings assigned to each Sunday and feast day of the church year. Many mainline denominations specify which translation is read aloud from the lectionary — the NRSV across much of Episcopal, Lutheran, and Methodist worship, for instance.
Deuterocanonical books (the Apocrypha): A set of books — Tobit, Judith, Sirach, 1–2 Maccabees, and others — included in Catholic and Orthodox Bibles but not in the 66-book Protestant canon. They were in the original 1611 KJV, between the Testaments, and a few translations still publish editions that include them.
