Are there any online tools that allow for searching of an english word to produce the gemara/aramaic translation?
I dont really mean translate, I mean to search the jastrow dictionary to find the translation.
You can search through the English definitions of the CAL Aramaic dictionary with the CAL Gloss Search. It includes a number of Aramaic dialects beside the Aramaic used in the Gemara, but if you are only interested in that dialect of Aramaic, then you can check the definitions for the abbreviation "JBA" (= Jewish Babylonian Aramaic) or "Com." (= Common Aramaic).
If a search of text will suffice, then you can do a search in online English texts of the Talmud, such as SEFRIA, or The Soncino Talmud Translation (HALAKHAH.com), and search for your English word and then see the corresponding Aramaic word in the original Gemara text. Good luck.
