The thing about grammatical gender is that it doesn’t really have much to do with sex or gender identity. In German, for instance, ‘mädchen’ (girl) is neuter. Gender in French is 98% assigned based on the pronunciation of the three final syllables. In Danish, living things tend to be ‘common gender’ and inanimate objects tend to be ‘neuter’.
It’d be more accurate to call it ‘noun classes’ than gender.
Well, as a German, I wouldn’t agree. Generally, nouns describing men are masculine and nouns describing women are feminine. “Das Mädchen” is just an odd one out because it’s the diminutive (always neuter in German) of “die Maid”, which in turn is feminine.
Yes, this doesn’t really apply to objects, but it mostly does for people.
Child - das Kind - grammatical gender: neuter. Referred to in context using the gender-neutral pronoun ‘es’ (it). The pronoun used correlates with the grammatical gender of the noun used, not the gender of the person referred to.
