The paper deals with the semantics of causal markers in polypredicative constructions; it is based on an areally and genetically balanced sample of 100 languages (Africa - 14 languages, Eurasia - 8 languages, Southeast Asia & Oceania - 13 languages, Australia & New Guinea - 27 languages, North America - 18 languages; South America - 20 languages; where the number of languages taken from each family depends on its size). The research is based on typologically oriented grammars, language descriptions, corpus data and consultations with language experts. It turns out that apart from their basic causal meaning, causal markers can express other additional meanings in the Reason clause, in the Result clause or in both of them. To my knowledge, a number of these parameters have never been mentioned in typological studies of polypredicative causal constructions. The most frequently mentioned additional meaning was evaluation, widely attested in European languages. Both positive and negative evaluation usually
