What's the main difference between "motif" and "motive?"

Native speaker’s answer

The difference is that a "motive" is a reason to do something, whereas a "motif" is a pattern or artistic idea or theme in something. Although, sometimes, the spelling of "motive" is used instead of "motif." Ex: The monologue's motif was about truth and honesty. = The monologue's motive was about truth and honesty. => less common Ex: I didn't have a motive to join the team. I just thought it would be fun. Ex: Did they find out the motive for the murder?
