The Words in Progress website is an online freely consultable database that is continuously enriched. It is included in the Aristarchus platform, a project of the University of Genova (Italy) which provides a set of working tools for research and teaching in the subject area of Greek and Latin ancient world. WiP represents an on-going supplement to the major currently used dictionaries of Ancient and Byzantine Greek and seeks to provide a scientific tool for scholars of Greek and more generally of the Ancient Greek and Latin world.
Drawing its inspiration from the over ten years of experience of the Poorly Attested Words in Ancient Greek, of which the materials form the basis for the new website, WiP aims to expand its objectives by detailing corrections and additions of many different kinds, in order to record recent progress in the updating and enlargement of lexica of Ancient and Byzantine Greek. Its primary focus of activity concerns the recording of new words, but attention is also devoted to previously unknown sources, novel acceptations and improvements of all kinds involving the entries in the main existing dictionaries.
WiP is open to collaboration and contributions from the scientific community: thus WiP welcomes any indications that would enhance the range of materials to be included in the database. Registered users can propose new lemmata.
