A prominent wallet is called monerujo (ujo makes the word mean container of monero), and the plural form of monero is moneroj. Monero itself of course is mono + -ero, so something like particle of money, like breadcrumbs are to bread or a grain of sand is to the sand as a whole. I'm ashamed that I only recently discovered that was an intentional thing, though the name has caught a sliver of my interest for at least a year now.
