(When) inflection needs derivation: a word formation lexicon for Latin

The Word Formation Latin (WFL) project has been awarded a Marie Curie Individual Fellowship to create a language resource consisting of a derivational morphological lexicon of the Latin language, which connects lexical elements on the basis of word formation rules. In WFL, lexemes are segmented and analysed into their derivational morphological components, in order to establish relationships between them on the basis of derivational or compounding processes. This chapter illustrates the methodology lying behind WFL, its lexical basis and the choices taken in order to maintain consistency in the resource, when encountering a number of cases raising theoretical issues. The online graphical query system used to access WFL is described, as well as a few examples of linguistic investigations that are made easier through the use of such a resource.
