agoraphobia, agorophobia: An excessive fear of crowded, public places (like markets), or of the necessity of leaving the sheltering protection of home, parents, friends, etc.; considered the most common phobia known.
The agoraphobic syndrome is a complex phobic disorder that often occurs in adults. The major features are a variable combination of characteristic fears and the avoidance of public places, such as streets, stores, public transportation, crowds, and tunnels.
The original definition meant "fear of going out into open spaces such as streets or isolated areas". Now it is applied to many disabling fears, usually involving a group of fears centering around a distance from a safe place. As a result, agoraphobics usually fear leaving home, going into the street, into stores, occupying center seats in churches, theaters, or public transportation, crowded places, large rooms where many people are gathered, or being far from help.
Alexander Karl Otto Westphal (1863-1941), a German neurologist, coined the term agoraphobia because the most distinctive symptom of the condition was anxiety that appeared when a phobic walked across open spaces or through empty streets.
He described this as the "impossibility of walking through certain streets or squares, or possibility of doing so only with the resultant dread of anxiety."
A common characteristic of agoraphobia is a history of panic attacks in which the person experiences symptoms of extreme excitement, distortion of perceptions, and an overwhelming sense of imminent catastrophe, loss of control, or fear of public humiliation. As a result, the fear then develops to such a degree that the individual begins experiencing anxiety in anticipation of panic reaction. One's reaction is the avoidance of the feared situation.

Agoraphobia is derived from the Greek agora which means an "assembly" or "market place"; not "open spaces", as is commonly stated by some writers. Again, agoraphobia refers to the fears of streets and crowded places, not to "open spaces".
