摘要：The main aim of this writing is to formulate the theory of Universal grammar: The. formulation made is taken from discussion on a close look at the universal grammarwhich of summary proposed by Greenberg and Hawkins. The items being searched arenot about elements such as subject,predicate,object respectively in sentence,but thecategories of words for example (N) & (V) in forming a simple sentence. The result of discussing universal grammar shows that (1) Chomsky's model uni- versal grammar states that all the natural languages include form and subtance universalgrammar;(2) Greenberg 's model of universal grammar devides languages in the world'into three types of universal word order (universal phrase sequence) = Verb + Subject +Object (VSO),Subject + Verb + Object (SVO),and Subject + Object + Verb (SOV);(3)Hawkins 's model of universal grammar states that based on word order;language theworld can be formulated into 24 types. Moreover;such types consist of groups of subtypeand category V,S,and O which are usually used to classify the type based on propositionand postposition,(4) the continued universal grammar states a different coocurence se-quence,which reveals comparison-base which is notS,V,o,but category such asN,V,N,N. The first N is subject,the second one is indirect object,and the third N is direct object. Inthis case il is clear that S or O is represented byN;(5) when there is sequence NNN uninsertedby V,a mark is needed to show which N as subject,device or indirect object,The mark canbe seen as in rowd order N before V is subject,or N after V indirect object,while the secondafier V is direct object. If the states of N-N changes,there must be a certain postverb(postposition) to indicate the indirect object;(б) the adposition of language with a patternVSO or SVO is preposition,while in the language SOV,the adposition is postposition..
