In German nouns carry a grammatical gender—which, for roles or job titles, is felt usually as masculine. Since the feminist movement of the 1980s, some writers and publishers have been using the feminine title suffixes "-in" (singular) and "-innen" (plural) to help boost the inclusion of women; but written with a capital 'I', to indicate that males are not excluded. Example: ("co-workers, <nowiki>male or</nowiki> female") instead of ("co-workers", masculine grammatical gender) or ("female co-workers"). This use is analogous to the use of parentheses in English, for example in the phrase "congress(wo)man."
