Abstract
The degrees of formality into which speech can be graded are in no sphere more obvious than in expressions of address and third-person reference. Methods of naming vary according to many factors: the formality of the circumstances in which naming takes place, the nature of the subject under discussion, and the ages, sex, and relative status of the speaker and addressee. Conventions of naming sometimes reflect the rigidity or otherwise of social divisions. In some societies or circles address between superior and subordinate is non-reciprocal: the speaker with the greater prestige will adopt one form of address, the subordinate another. In other societies when unequals address each other both may use the same formal method of address: the difference of prestige is not explicitly acknowledged.
