The suffix -ess has been used since the Middle Ages to form nouns denoting female persons, using a neutral or a male form as the base （as hostess and actress from host and actor, for example）. Despite the apparent equivalence between the male and female pairs of forms, however, they are rarely equivalent in terms of actual use and connotation in modern English （consider the differences in meaning and use between manager and manageress or poet and poetess）. In the late 20th century, as the role of women in society changed, some of these feminine forms have become problematic and are regarded as old-fashioned, sexist, and patronizing （e.g. poetess, authoress, editress）. The 'male' form is increasingly being used as the 'neutral' form, where the gender of the person concerned is simply unspecified.
