There are various other big dictionaries and websites specific to different dialects, but I don’t want to have to search on each of them by hand.
I’m currently working on a meta-dictionary, which is a fancy name for unique search engine for all the dictionaries I can find out there. It’s not finished but so far it works great; I use it almost daily.
I started with Phoenix (Elixir framework) and Svelte to learn them but I ditched Phoenix because it was a hell to work with how implicit things are there (no import; just assume that variable is defined "somewhere") and went back to a very basic Python Flask app that serves an API for Svelte.
Nothing very fancy on the tech side but it’s interesting to deep dive in the languages of Italy and learn a lot of things about both Italy and linguistics at the same time.
