Often it is a struggle to keep up with the Hebrew and Greek vocabulary learned while in Bible college or seminary, but VocabWorks is a free flashcard program that really helps. It includes vocab sets for Biblical Hebrew and Aramaic and Koine Greek. It also includes sets for Meroitic, Ugaritic, and Middle Egyptian, for the really hard core ancient language types.
The Hebrew downloads section includes a vocab set for Jan Verbruggen's Workbook for Biblical Hebrew. And the Greek downloads section include vocab sets for John H. Dobson's Learn New Testament Greek, William Mounce's Basics of Biblical Greek Grammar, and J.W. Wenham's The Elements of New Testament Greek.
The program is also helpful for professors who want an easy way to develop vocabulary tests for their students.
Although it doesn't appear that the software is still supported, I have never had any trouble using it. At any rate, it's free! So why not give it a shot?
