In the1930s, the sources of the standard norm were based on Ertl’s “good author” theory, lan- guage consciousness, and the oral practices of the intellectual class according to the Prague School of Linguistics. In the 1950s, the sources of the grammatical norm were amplified. In the 1960s, spoken Czech, especially the variety known as “common Czech”, came forth, with the central basis for investigating the standard norm formed by technical and journalistic texts. After the linguistic-pragmatic turn in the 1970s and 1980s, style and communication norms also began to be considered in addition to the standard norm. The plurality of opinions and the revocation of the opinions of the 1930s and the 1960s are typical for the present postmodern period. In this article, the author presents his own hierarchy of sources. In accordance with A. Jedlička and A. Stich, he regards technical and journalistic texts as the most important source, followed by fiction and spoken literary Czech texts.
