The collocations were excerpted from official texts found on notice boards in Tarnów district. They were analysed in three aspects: methodological and structural, lexicographical and educational. First, the subject of the text containing collocations was defined, then their formal and grammatical structures were described as well as their lexical contents. The collocations were classified into four groups concerning whether the words used in them belong to general Polish or are used only in its certain variants. As a result the author could describe how many idioms are found in different classes of collocations and he proposed new, rational way of teaching idioms at school.
