The famed three-volume Georgian-German dictionary by Kita Tschenkéli (კიტა ჩხენკელი), “Georgisch-Deutsches Wörterbuch”, which is the best bilingual dictionary of Georgian into any language, including English and Russian, is in print again!
When I studied Georgian in Tbilisi, my dad had to get all 2508 pages photocopied from the university library’s copy and sent to me because it was absolutely essential but impossible to buy anywhere.
The price is €145, which is really quite cheap for this type of work. The only reason I’m not ordering it is because I still have my prized photocopies.
They’re also selling his excellent Einführung in die Georgische Sprache at €75. This is not essential in the same way, but it’s definitely worth having if you’re serious about learning Georgian. I don’t own it, but I’ve spent many happy hours with it in the library of the Department of Linguistics in Aarhus.
