This paper deals with the topic of adverbs as morphological types with an emphasis on their correct and incorrect use in public media and in the language of the student population. The research for this paper is based on the analysis of the professional work of Maja Glušac (year), who singled out examples of improperly used adverbs from various public media, which are represented in the language advice of numerous recent Croatian language advisors. For the purposes of this work, according to the examples on Google, a form was created to check students' knowledge of adverbs as a morphological type and their knowledge of the standard language, i.e. the correct form of these adverbs, determined on the basis of linguistic advice. After analyzing the obtained student results from the form for checking their knowledge about the use of adverbs, it was possible to conclude that most students know adverbs well as a morphological type. Regarding the language tips and the public use of adverbs according to them, the majority of students correctly chose the correct forms of adverbs of place, quantity and manner by two-thirds of the time, but they chose one part of time adverbs incorrectly by two-thirds. The aim of this paper was to warn, based on adverbs as a morphological type, of the inconsistency of their use in the Croatian public language with its standard linguistic norm and how this is reflected in the knowledge of the student population about the correct forms of adverbs.
