The Etymological Wordnet project provides information about how words in different languages are etymologically related. The information is for the most part mined from Wiktionary. The semi-structured data is turned into a machine-readable etymological database that also incorporates some additional manually added etymological relationships.
A very basic interface to the data is provided at lexvo.com. A more advanced browsing interface will be available later.

Please get in touch with Gerard de Melo, if you would like to contribute to the Etymological WordNet, or if you have additional suggestions or research proposals. There are several ways in which the data could be improved if you have a specific research project in mind.
Who would have thought that the English word "muscular" and the German word for the animal "bat" share the same origins?
The Etymological WordNet is just one of several linguistic and lexical-semantic resources that we provide. Please see the Resources section for other resources, including UWN, our large multilingual network of word senses with millions of semantic relationships.
