The answer is: an emotion that is expressed by people in all cultures.
An emotion is a mental state that relates in different ways to thoughts, feelings and bodily states or responses, which makes them also relate to the perception of pleasure of pain.
A basic or primary emotion, as many researchers have tried to prove (like William James or Paul Ekman) is one that is believed to be experienced by any person in any given culture and whatever point in history, that is to say, they are universal. Although the list of basic emotions is versatile and many researchers have contributed to it, some of the most widely accepted basic emotions are: excited, tender, scared, angry, sad, and happy.
