The term "Haykabanutyun" often comes across in scientific literature and fiction. The concept of "Haykabanutyun," however, hasn't been defined so far and we cannot explain what did Haykabanutyun/Haykaban specifically mean. The author tackles this concern in this article, based on diverse dictionaries and other sources. He argues that though the term maintained a broad sense, it was used with various connotations in different periods and by different scholars. Eventually, he combines the diverse sets of meanings and presents the reader with some of its characteristic objectives: a. to prevent the Armenian language from the impact of Latin and maintain its purity. b. to use only the 5th century classic Grabar (Old Armenian) words, and grammatical expression. c. to make the Armenian language more perfect and artistic based on the 5th century linguistic achievements. d. to spread Armenian education in educational institutions. e. to avoid the influence of other languages and dialects on the Armenian language. Those who had adopted such a policy were called "Haykaban"s.
