What is “Strong’s Definitions?”

“Strong's Definitions” is a collection of the unique Greek and Hebrew words and their definitions from the Old and New Testament, organized by Dr. James Strong in 1890. All the original words are organized in their alphabetical Greek/Hebrew order, and are numbered regularly from the first to the last. This makes referencing easy without recourse to the Greek/Hebrew characters. Each word is followed by its equivalent in English letters, according to the system of transliteration. Following the transliteration is the precise pronunciation according to the usual English mode of sounding syllables, in such a way that any Græcist would immediately recognize the word if pronounced, notwithstanding the minor variations current among scholars in this regard. The same method is used in the case of proper names, as well as a regular mode of Anglicizing it, after the general style of the Common English Version, and a few words of explanation are added to identify it. After the punctuation-marks ":—" are given all the different renderings of the word in the Authorized English Version, arranged in the alphabetical order of the leading terms.

Where did we get it?

“Strong's Definitions” is available for free through the public domain and was used as our source material. Over time we have refined the definitions and updated them manually according to a physical copy of “Strong's Definitions” and Perschbacher's Analytical Greek Lexicon. Our descriptions thereof are based upon those found in The New Strong's Exhaustive Concordance of the Bible.


There are, in fact, 100 missing Strong’s Numbers: 3203-3302. This is not because we have misplaced them, rather because of “changes in the enumeration while in progress.”

As well, not every distinct word is assigned a number, rather only the root words. For example, “αγαπησεις” is assigned the same number as “αγαπατε”, so they are both listed under G25 for “αγαπαω.”
