The question of information security is also studied by applied linguistics, especially in the current Ukrainian political and economic realities. - Today, we understand how important various areas of applied linguistics are. The language is interpreted as a weapon. This was mentioned by Lesia Ukrainka, and known cognitive linguist Professor Svitlana Zhabotynska. Unfortunately, we know not merely the "hot" and "cold" war, but a war of ideologies that came forth in the postmodern era and does not fit to the typical criteria of information warfare. War theatre operations are our awareness. At the same time for it fights are carried. We have to sharpen our language to win this war, - Says Olena Levchenko, head of AL Department Around six dozen participants from different cities of Ukraine came for the conference, as well as scientists from Poland, Austria and the Czech Republic.
