In this paper we present the linguistic databases developed during our 8-year lexicographic research on the Modern Greek Standard (MGS) verbal system. Apart from the intermediate databases presented, the main products are (a) a new conjugation system of 385 paradigmatic models, which allows for the automatic generation of all verbal lexical morphemes and monolexical forms (b) a statistically established database of 151,536 distinctive verb-final grapheme sequences which allow for the automatic tagging of all monolexical verbal tokens without the traditional intervention of any built-in lexicon, and (c) a linear Iemmatisation morphophonological rule system accessed on the basis of the distinctive grapheme sequences identified.
