Abstract
Women use linguistic forms associated with the prestige standard more frequently than men. One reason for this is that working-class speech has favourable connotations for male speakers. Favourable attitudes to non-standard speech are not normally expressed, however, and emerge only in inaccurate self-evaluation test responses. Patterns of sex differentiation deviating from the norm indicate that a linguistic change is taking place: standard forms are introduced by middle-class women, non-standard forms by working-class men.
