	abstract = {The present attempt at the taxonomy of speech values is based on the most general theoretical principles of the unity of act, sound structure, social value and is a continuation of the author{\textquoteright}s paper on the system of speech ways. The approach aims at establishing the universal features in languages as act-and-value systems. Taxonomy is assumed to be based not on words considered in the case as complex idiom-like structures, but on the semantization of speech acts and their respective features in the sound structures. The dependence of the values on the speech acts and ways comes to the fore: this approach is different from most existing semantic taxonomic theories which are based on the so-called conceptual meaning of words and are, therefore, hardly differentiated from taxonomies in the respective non-linguistic sciences. This dependence can be called an inner motivation of the sound structures and their respective values in contrast to the ideophonic and derivational motivation of the word. It is presumed that, in so far as the speech ways are universal. anguages will exhibit a greater uniformity when studied contrastively.},
