Entitlement is a guarantee of access to benefits because of rights, or by agreement through law. It also refers, in a more casual sense to someone's belief that he/she is deserving of some particular reward or benefit.http://writ.news.findlaw.com/hamilton/20030828.html It is often used as a negative term in popular parlance (i.e. a 'sense of entitlement'). The legal term, however, carries no value judgment: it simply denotes a right granted. In clinical psychology and psychiatry, an unrealistic, exaggerated, or rigidly held sense of entitlement may be considered a symptom of Narcissistic Personality Disorder.
