“Sublunary” is based on the Latin “sublunaris,” which combines the prefix “sub-,” meaning “beneath,” and “lunary,” meaning “of the moon.” The adjective can be used to describe the often mundane circumstances of the world, in contrast with loftier or more spiritual matters. While wondering about something like what to make for dinner might seem boring in comparison to high-brow debates, the sublunary is what makes the world turn. For example, “The city council asked speakers to limit philosophical discussions so they could quickly get to the sublunary concerns shared by residents.”
