Personality is

the particular combination of emotional, attitudinal, and behavioral response patterns of an individual. Different personality theorists present their own definitions of the word based on their theoretical positions. Psychologists such as Freud, and Erickson have attempted to come up with personality theories.

In psychology, the Big Five

personality traits are five broad

domains or dimensions of personality that are used to describe human personality. The theory based on the Big Five factors is called the Five Factor Model. The Big Five factors are openness, conscientiousness, extraversion, agreeableness, and neuroticism.

Personality disorder refers to a

class of personality types and enduring behaviors associated with significant distress or disability, which appear to deviate from social expectations particularly in relating to other humans.
