Grammatical gender
A word's gender decides how to say a word. For example, the German word for man is masculine (der Mann), the word for woman is feminine (die Frau), and the word for girl is neuter (das Mädchen). The gender of a word may not have connection with its biological sex in certain languages; it is instead a way to organize words grammatically. Many Indo-European languages, like Russian, German, and Latin, still have all three genders.
