Abstract
Language plays a great role in how people perceive the world. It is first of all a means of forming ideas that manifest themselves in speech. Words used in a language have an immeasurable power. They have the power to inspire, motivate or persuade people on one hand and evoke emotions and shape opinions on the other. They give out energy as well as convey certain message that can have a peculiar effect on a person. So, words can affect humans in various ways. Thus, the use of power words is not stable and it can change from person to person, from culture to culture, from age to age. The aim of this article is to demonstrate that the use of power words can serve as a means of both constructing and deconstructing a speech. Studying English power words is essential in various fields, including psychology, linguistics, communication, rhetoric, etc. To achieve this aim rhetorical questions, political discourse and emotional words have been analyzed.
