Is there an online glossary anywhere that explains important Talmudic terms, with similar scope to the Practical Talmud Dictionary? I'm more interested in an Aramaic-English resource, but Aramaic-Hebrew would be useful as well.
There's also the Jastrow online.
But that might be overkill, by the standards of Frank.
i have a gemara glossary and a rashi glossary online
Wikisource has A Dictionary of the Targumim, the Talmud Babli and Yerushalmi, and the Midrashic Literature
Also in the possible overkill category is Yad Malachi, which is available freely and publicly on hebrewbooks.org and also included in the Bar Ilan database. It explains terms, logical structures, patterns, and methodology of the G'mara.
