In this paper we attempt to introduce a new teaching method for Spanish grammar education, based on the Movement theory of the Generative Grammar and we want to show that this new method can explain Spanish grammar phenomenon more easily and effectively than the existing school grammar. For this purpose, we start with some nominal phrases and simple sentences of the Korean and Spanish languages. We find out the basic difference of the two languages by comparing their nominal phrases and simple sentences from the point of view of Movement theory. The difference is that the Korean language does not have movement phenomenon but the Spanish language does. This difference is consistent in all of complex clauses with relative pronouns. We show that with this theory we can teach Spanish nominal phrases, simple clauses, exclamative clauses and relative clauses in a unitary and effective method of explication without a supposition ad hoc.
