Disgust is a term based on the word "disdain". Many specialists in the field of philology cannot say exactly what it really means. Some scientists claim that this expression is somehow connected with sour or fermented milk, while others consider it to be a description of a dismissive look and a snobby upturning of the nose. Many do not notice that these hypotheses, despite their fundamental differences, have one thing in common. And in the case of the first option, and in the case of the second, a person, judging by his gestures and facial expressions, experiences the same feeling - disgust. He turns his head away, tries to close his nose so as not to hear an unpleasant smell, tightens his lips and in other ways shows his negative emotions. In short, disgust is a feeling of disgust and disgust for everything unclean.
