This is often apparent from the sound or spelling of a word, rather than any genderedness in its concept. A chair is une chaise (feminine), and it would be weird for chaise to be masculine. It’s not because the chair is feminine, it’s because the word is. There are some rules that help you figure out the gender based on the word (often what sound the word ends with), but there are exceptions to those rules.
Livre (book) is actually an example of where the gender creates a different meaning: un livre is a book, while une livre is a pound (the unit of weight).
