Technical terminology evolves due to the need for experts in a field to communicate with precision and brevity but often has the effect of excluding those who are unfamiliar with the particular specialized language of the group. This can cause difficulties, for example, when a patient is unable to follow the discussions of medical practitioners, and thus cannot understand his own condition and treatment. Differences in jargon also cause difficulties where professionals in related fields use different terms for the same phenomena.
