This paper provides a systematic and concise overview of the norms in the language, characteristics of the standard language, and the variations in the language itself. Language is a special system that has its own specific structure and prescribed standards of use. The aim of this paper is to study and briefly explore non-standard varieties, their use in public communication, and people's attitudes toward the occurrence of using non-standard varieties in a particular situation that requires standard language. The paper begins by outlining some of the main tenets of linguistic regularity and basic principles in language. It further deals with language varieties and public discourse as well as the standard and standardization process in general. At the end of the paper, the facts and attitudes towards the use of non-standard varieties in public discourse were presented, which were obtained by a short survey of about fifty respondents. The results are different depending on whether they are younger or older, and more or less educated. Summarizing and taking into account most of the answers and results, we can conclude that the majority of respondents consider that the use of non-standard varieties in public communication is utterly inappropriate.
