Linguistic variety on a large scale, within one and the same community, is, both laymen and linguists, usually dealt with in terms of variety. Other terms such as patois, brogue, 'bable', 'Platt', refer to varieties which are ultimately presented under the rubric of dialectology. Any attemps on the part of specialists to use these terms without previous redefinition is likely to be unsatisfactory because they are, in fact, quite unspecific designations used, with a touch of contempt, by standard speakers in reference to any speech variety that is not socially acceptable.
