 Those that are not accented on the ultima usually raise the accent in the neuter.Another group includes adjectives that end in -υς ([-is], "-ys").Although some are declined somewhat archaically such as οξύς ("oxys", "acute"), most of them are declined according to the rules of Demotic Greek and in many cases and persons they acquire other endings, such as in the case of πλατύς ("platys", "wide").
