It seems that there are certain linguistic situations ideally adapted for the usage- based approach and the Greek case is one of them. This is a corpus-based study,which is based on the analysis and processing of a large variety of Greek texts ineveryday spoken interactions. As our starting point, we argue the panchroniccharacter of Greek lexicon, its extreme conservatism and the man-made character ofthe formation of the Greek literary standard. Some practical issues such as thechoice between monotonic and polytonic orthography, lexemes tagging to obtainmore data are addressed here.
