The Central Slovenian literary language between the 16th & 19th cc. did not make good use of the expression with participial & gerundival forms in -c & -si, in fact, they were nearly forgotten. They were brought back to life in the 19th c. under the influence of the Prekmurje literary language & following the example of OCS. In the uniform Slovenian literary language of the second half of the 19th c., the forms in -c & -si became fashionable & extremely literary, but at the end of the century with the arrival of the Slovenian Moderna they again retreated to the linguistic periphery, where they survive in expository & journalistic language as an effective syntactic condenser & means for the hierarchization of actions.
