Gender from french genre, latin genus, means category and that's all it is, a category system, with confusing category names and no real rules for which word belongs to which category. There's nothing masculine, feminine or neuter about words, nothing "sexual" or whatever, otherwise every person would be a woman because the word for person (from latin persona) is feminine in a lot of european languages, or French and German people would have to think really different about stuff like tables because in French it's "feminine" and in German it's "masculine". Btw, looking at English adjectives with French origin they almost always are the feminine version, like feminine or masculine. Some people think there is a hidden sexual meaning though and they come up with lots of different systems for gender neutral language, stuff like latinx.
