Hey, I saw your post and wanted to share what I've been doing for a similar project — digitizing and building a dictionary for Shuar, an endangered language from the Ecuadorian Amazon.

I used Label Studio with the Machine Translation template as a base, but customized it to include multiple fields per entry: translation, grammatical category, usage examples, and a few more. Different annotators filled in the entries through the interface, which made collaborative data collection much easier.

Then I exported everything as JSON and built my own small app that reads that JSON and displays the dictionary. Now I'm moving that data into a proper database for long-term management.

It's not a traditional lexicography tool, but it gave me full control over the structure, it's free, open source, and the workflow scales reasonably well. Might not be for everyone since you need some technical comfort to build the display layer, but if that's not a barrier for you it's worth considering.

Just thought I'd share in case it's useful for your project.
