Abstract: DialG is an Interactive Diachronic Greek Dictionary, which takes into account (with its ultimate goal to integrate) all previous scientific dictionaries (including ancient, medieval and modern Greek). It takes the form of a database, which will be continuously updated. The dictionary is open to additions, to new entries and to additional information (types and meanings), which are not thus far included in DialG. Thus we will eventually have access to an important tool for Greek texts of all periods.
