A PAPER by M. Talmey on the auxiliary language question, in which the value of an auxiliary language as an agency for world peace is discussed, has been reprinted from the Modern Language Journal of December 1938. Dr. Talmey discusses the basic requirements of an auxiliary language, particularly the importance of being more expressive than the natural languages and strictly neutral. It must also be as suitable for the expression of all ideas as the most efficient natural languages are. He discusses the development of Esperanto in the United States and the reasons for its failure, and then describes the origin and development of a new international system known as ‘Arulo’ or ‘Gloro’, which aims at removing the ambiguity which characterizes most modern languages. In this system the main parts of speech are recognizable by characteristic endings, of which there are eighteen, six occurring very rarely. He suggests that the fitness of a language for translation is the best criterion of its efficiency.
