This paper aims to survey the aspects of the case and to trace how the English case system and adpositions relate each other based on the universal typology. It is observed that each language has a unique case system, but we are able to find out some meaningful generalizations on the basis of the typological approach. Languages can be classified accusative, ergative, tripartite and neutral languages as how each related to the S(subject), A(agent), and O(object). There are three different ways to designate the case; by word order, NP-marking and cross-reference. In NP-marking, either declension or adposition is used to mark the case. Since it is observed that using adpositions is the most frequent way to mark the case, we can find the significant universality: adpositions have various functions not only of marking cases but of linking words, modifying nouns and adverbs. Adpositions are originally derived from content words such as nouns, verbs and adverbs. Each adposition had its own concrete meaning, but as time goes by, it has extended to have abstract meaning.
