The TWOD entry reads:
- [hap-aks luh-gawm-uh-nawn]
(Greek hapax, once + Greek legein, to count or to say = once said)
This is a word that only occurs once in a particular body of literature. With regards to the Scriptures, exegetes will often find a word that only appears one time. In the New Testament alone, there are 1,932 words that occur only once (USB). When this happens, it is often difficult to determine the exact meaning of the word because there are no other usages with which one can compare it.
Note that Romans and 1 Corinthians contain the most single-occurrence words. The chart is based upon Grimm-Thayer's "Lexicon" and indicated the following numbers of hapax legomena: Rom. 113, I Cor. 110, II Cor. 99, Gal. 34, Eph. 43 Phil. 41, Col. 38, I Thess. 23, II Thess. 11, Philem. 5, I Tim. 82, II Tim. 53, Titus 33.

An OT list claiming about 1500 of these words is shown here:

Does anyone know where a complete list of these words exists for the NT online? I don't have Accordance software (no longer use Apple's computers) to do a search on my own.
