neologisms

From
http://en.wikipedia.org/wiki/Neologism

A neologism (pronounced /niˈɒlədʒɪzəm/); from Greek νέος (neos 'new') + λόγος (logos 'word') is a newly coined word that may be in the process of entering common use, but has not yet been accepted into mainstream language. Neologisms are often directly attributable to a specific person, publication, period, or event. According to Oxford English Dictionary the termneologism was first used in print in 1483.

Other uses

In psychiatry, the term neologism is used to describe the use of words that only have meaning to the person who uses them, independent of their common meaning.^[1] This is considered normal in children, but a symptom of thought disorder (indicative of a psychotic mental illness, such asschizophrenia) in adults.^[2]

People with autism also may create neologisms.^[3]

Use of neologisms may also be related to aphasia acquired after brain damage resulting from a stroke or head injury.^[4]

In theology, a neologism is a relatively new doctrine (for example, rationalism). In this sense, a neologist is one who proposes either a new doctrine or a new interpretation of source material such as religious texts.^{[citation needed]}
