They say grammar rules convey sexist ideologies and should be reformed.

French grammar says that when the subjects of a sentence are feminin and masculin, the verbs and the adjectives of the sentence agree with the masculin not with the feminin.

The French say "les hommes et les femmes sont beaux" and not "les hommes et les femmes sont belles", which translates as "men and women are beautiful".

Several feminist organisations say this rule was introduced in the 17th century when grammarians decided the masculin was "nobler" than the feminin. Feminists want to scrap this rule.
