SSWL is a searchable database that allows users to discover which properties (morphological, syntactic, and semantic) characterize a language, as well as how these properties relate across languages. This system is designed to be free to the public and open-ended. Anyone can use the database to perform queries.
To read about early updates, please visit our Google Group, (which is no longer actively used).
This site hosts the original prototype SSWL, launched June 1 2009.
