Type-Verbs and Token-Verbs in Japanese Play

Type-Token distinction and Figure and Ground relationship are dichotomic model to explain how human distinguish vary notions. This research inspects a relationship of these two relationships in Japanese plays. At first we make two series of lattices from the rough set to show figure and ground relationships in each scene. One series are made by verbs mentioned in speech. These are defined as "type-verbs". Another are made by verbs actually did in play by some characters. These are defined as "token-verbs". Compared change of complementarity and non-distributivity of lattices about type and token verbs, in short plays two series of complementarity differ beginning to ending but in long plays they accord in ending.
