The aim of this paper is to offer a brief insight in the field of euphemisms in the English language from different points of view. First of all, I have represented some basic definitions and terms related to euphemisms according to some relevant linguistic research studies. Since I was exploring medical euphemisms, the explanation of some basic principles of medical communication has also been included in my work. Based on the relevant sources a brief overview of the factors which play an important role in medical communication has been included. While trying to define the role and importance of euphemisms in medical communication the use of euphemisms in some specific medical situations and diagnoses such as heart failure, cancer and some other mortal diseases in general has been studied. I have taken into consideration relevant research works on the opinions of medical workers and the patients on the use of euphemisms and medical communication. The representation of Warren´s model of euphemism has also been incorporated in this paper and the corpus of the paper has been analyzed according to her principles. Finally, I have come to the conclusion that euphemism, despite being a linguistic unit, and their usage are significantly influenced by many extra-linguistic factors.
