| Research Abstract |
We conducted a constructive study on the origin and evolution of language focusing on grammaticalization and displacement which are particular and universal features of human languages. We claimed that the ability of linguistic analogy, which is to extendedly apply acquired linguistic rules, plays an important role to develop acquirable and changeable languages and to bring out displacement, and thus, this ability should emerge at the origin of language. Further, we showed that metaphoric and metonymic inferencing bring unidirectionality from concrete to abstract, which is an important feature of grammaticalization.
