Jealousy is an emotion, and the word typically refers to the thoughts and feelings of insecurity, fear, concern, and anxiety over an anticipated loss or status of something of great personal value, particularly in reference to a human connection. Jealousy often consists of a combination of emotions such as anger, resentment, inadequacy, helplessness and disgust. In its original meaning, jealousy is distinct from envy, though the two terms have popularly become synonymous in the English language, with jealousy now also taking on the definition originally used for envy alone. Jealousy is a typical experience in human relationships. It has been observed in infants five months and older. Some claim that jealousy is seen in every culture; however, others claim jealousy is a culture-specific phenomenon.
