Rambam = Rabbi Moshe Ben Maimon = Maimonides
Where does “Maimonides” come from? Sounds Greek. I doubt Rav Moshe ever called himself that.
It’s actually a Ladino root.
I promise that neither he nor any Rabbi who got an acronym, Rashi, Rambam, Rambn etc… ever called themselves by such an honorific. If you were his friend, he probably went by Moshe. I’m sure that’s what his wife called him.
