A dictionary that understands what you're looking for.
(... And is mobile-friendly!)
Everything (or, well, almost everything) that concerns minority languages should be free. Here you'll find free dictionaries, and other analytical tools.
Everything here is based on open-source tools. Do you have an idea for an app or research project that needs linguistic resources? Visit Giellatekno's website for information on how to get access to lexicon files, and morphological and syntactic analyzers.
Write what you wish, and the dictionary will analyze it to break apart compound words and find base forms.
