A Comparison of Unish Grammar with Esperanto

The purpose of this paper lies in claiming that the grammar of Unish， which has been being developed at Sejong University， is simpler， more logical， and more regular in many aspects than that of Esperanto， which was created more than a century ago. The validity of this claim is checked by comparing Unish with Esperanto with regard to several main parts of grammar such as the formation of interrogative sentences and passive sentences， the system and use of personal pronouns and relative pronouns, the nonuse of expletives， and the non-occurrence of agreement in a noun phrase. On the basis of these comparisons this pa per concludes that it is easier to learn and use Unish than Esperanto.
