Natural Language (NL) is the most amazing of the phenomena worthy of attention of scholars. It is the might and the indicator of weakness of one’s intelligence, the truth messenger and liar. We hope we know it, and still, when speaking, we fear to look clumsy. It seems, in investigations we sometimes sooner guess its properties and laws than recognize them by analysis on the basis of some accepted method. In the present section the levels of language – such as morphology or semantics – are examined.
