The word charisma refers to a rare trait found in certain human personalities usually including extreme charm and a "magnetic" quality of personality or appearance along with innate and powerfully sophisticated personal communicability and persuasiveness; in short, charisma is often used to describe a seemingly uncanny ability to charm or influence people.
It refers especially to a quality in certain people who easily draw the attention and admiration (or even hatred if the charisma is negative) of others due to a "magnetic" quality of personality or appearance.
Though the term as it stands is extremely difficult to define, other similar terms related to charisma include: grace, exuberance, equanimity, mystique, positive energy, joie de vivre, extreme charm, personal magnetism, personal appeal, "electricity," and allure, among many others.
Another term constantly used is the "X-factor." Usually many of these qualities must be present within a single individual for the person to be considered highly charismatic by the public and their peers.
Despite the strong emotions they so often induce in others, charismatic individuals generally project unusual calmness, confidence, assertiveness, dominance, authenticity, and focus, and almost always possess superb communication and oratorical skills.
