One of the simple prepositions, namely `se', when followed by the definite article, is fused with it and forms what we call prepart: `ston' (`se' + `ton'), `styn' (`se' + `tyn'), `sto' (`se' + `to'), `stous' (`se' + `tous'), `stis' (`se' + `tis'), `sta' (`se' + `ta'). These forms are further coded for the morphological features of the article (i.e. Gender, Number and Case). Note that for these features, not all case values are possible (only the genitive and accusative).
