Croatian standard language is defined by rules, i.e. norms, and therefore standardization is one of its most important features. Other important features are autonomy, polyfunctionality and stability in space and time. Numerous authors in their works discuss the Croatian standard language, its features, the relation of linguistic system and standard language and the principles of the Croatian standard language. The purism is also an important feature of the Croatian language and language advice handbooks show the purist aspiration of the Croatian standard language. The standard language is a complex sysytem, not spontaneously acquired, thus necessary to lear. Everyone has the same opportunity to learn how to use it. The language c books on how to use different language features, help Croatian speakers to learn the Croatian standard language. This study will show older and newer language advice handbooks (six in total) in order to emphasise the differences between them and their purpose and function. In addition to the interpretation and analysis of language advice handbooks, this study explores the representation of normative recommendations in textbooks for elementary school. There were analized 19 textbooks from various Croatian authors, from first to fourth grade of elementary school. The study of these textbooks has identified the type and scope of language advice as well as their use in the elementary school.
