The correct use of our language is the first part of the book where the monotonic, word separation, punctuation, formal words, foreign words, and various cases of common grammatical, spelling, syntactic, and semantic errors are examined in detail. In controversial points, after presenting the opposing argument, an attempt is made to distinguish the most correct position (which may not always be the prevailing one), in order to achieve a more comprehensive approach to the specific problem. At the end of each chapter, there are usually exercises aimed at a more complete understanding and consolidation. Indicative answers to these exercises are given in the third part of the book.
