There are many ardent Indesign users from Georgia and as yet there is no official Indesign dictionary. Peolpe manually creates extension files for the dictionary, writes them and also adds the Info.plist file to make it work somehow. I've done it on Windows too and it works, but it kind of doesn't work for Big Sur on mac and Indesign version 16. It will be best if you help design the Georgian language as well. If you'd like, I can send you some ready-made dictionary and spelling files for the Georgian language that I created myself for you to check too. I very much hope that you will hear my request and add another ancient language to this design tool
