In languages that distinguish between masculine and feminine plural pronouns, such as French or Serbo-Croatian, the masculine is again often used as default. ""Ils vont à la bibliothèque"", ""Oni idu u biblioteku"" ("They go to the library") may refer either to a group of masculine nouns or a group of both masculine and feminine nouns. ""Elles vont..."", ""One idu..."" would be used only for a group of feminine nouns. In many such languages, the gender (as a grammatical category) of a noun is only tangentially related to the gender of the thing the noun represents. For example, in French, the generic "personne", meaning a person (of either sex), is always a feminine noun, so if the subject of discourse is "les personnes" (the people), the use of "elles" is obligatory, even if the people being considered are all men.
