摘要

To further clarify the elements essential for the composition of a speech community and to prove their due important roles, this paper, taking the speech community in the medical domain as an example, analyzes the five relevant elements from the perspective of their dominant and recessive attributes in various conditions. It is stated that if all five key elements show their dominant attributes in a speech community, the speech community can be regarded as a typical speech community; in comparison, the recessive display of any of the five key elements may make speech community a marginal one.
