Pocket Dictionary of Biblical Studies
Arthur G. Patzia; Anthony J. Petrotta
A compact glossary of more than 300 terms from the field of biblical studies — covering textual criticism, hermeneutics, archaeology, and the vocabulary that fills introductory seminary courses. Useful for anyone who keeps hitting unfamiliar words in a commentary or course textbook and wants plain definitions without having to dig through a full academic dictionary.

Pocket Dictionary of Theological Terms: The IVP Pocket Reference Series
Stanley J. Grenz; David Guretzki; Cherith Fee Nordling
Covers the theological vocabulary that comes up constantly in sermons, seminary reading, and faith discussions — from atonement to theodicy — in short, accessible entries. A good first reference for anyone who wants to read theology without stopping every page to look up what a term means.

Pocket Dictionary of Apologetics and Philosophy of Religion
C. Stephen Evans
Defines the key terms and introduces the major thinkers and movements across two closely related disciplines: Christian apologetics (making the case for the faith) and philosophy of religion (examining religious belief through reason). Written for students entering either field who need a reliable reference for the vocabulary before they can follow the arguments.

The Baker Expository Dictionary of Biblical Words
Tremper Longman III; Mark L. Strauss
Traces individual words through their Hebrew and Greek roots and shows how their meaning carries across different passages of Scripture. Organized by English word, so readers without knowledge of the original languages can use it directly — helpful for preachers and teachers who want to explain what a word actually meant in its original context.

Mounce's Complete Expository Dictionary of Old and New Testament Words
William D. Mounce
A single-volume word study resource covering both Old and New Testament vocabulary, organized by English entry so it works without any knowledge of Hebrew or Greek. Each entry explains what the underlying word means in its original language and how that meaning plays out across Scripture.

Vine’s Complete Expository Dictionary of Old and New Testament Words
W. E. Vine; Merrill Frederick Unger; William White Jr.
One of the most widely used word-study references in English Bible study. Vine's original New Testament section is known for its careful attention to the range of meanings individual Greek words carry across different contexts. The Old Testament supplement by Merrill Unger extends the same approach to Hebrew. Keyed to Strong's numbers throughout.
