Croatian literature even in the old ages tends to stay away from barbarisms and foreign words, a certain conscious care in the works of literature is felt when it comes to language selection. In the course of centuries hence the tendency is formed for literary language to be as much as pure and selective as possible. One thing is the colloquial language, often ridden with foreign words, and entirely different thing is the language of literary works in which tendency for language purity arises. The way and the extent to which that need could be satisfied is different in various periods, but the tendency for as pure and selective language can be noted even in Old Dubrovnik writers, and in Vitezović. All the way to pre-Illyrian and Illyrian efforts and by the end of the XIX. century, when the osmotic influence of traditional Croatian literary heritage does not cease to stop...That care of language purity which characterizes Croatian literary expression even in the XIX. century, remains immanent in later periods...Literary language of the Croats is in fact organic continuation of older state of affairs in Croatian literature.
