Ever wonder what rude and rudimentary have in common? They sure sound alike…but these days, rude indicates bad manners, and rudimentary means basic. Are they related?
You bet they are! Both come from the same Latin root, rudis, which means “rough, crude, unlearned.” Think of this not as necessarily bad, but as “raw”–from there, rude came into English meaning the same thing by the late 1200s, with that sense of “coarse, unfinished.” But it only took about a hundred years for people to begin applying it to each other when they did mean something negative–because if one’s manners are raw and unfinished and coarse, that usually meant one “ill-mannered, boorish, ignorant, uneducated” or “marked by incivility.”
As for rudimentary, it starts from that same root, but didn’t become a word until 1819, but from the 1500s onward we had the same meaning carried in rudimental. Here, they both mean “undeveloped or elemental.” Rudiments is also from the 1540s, with that meaning of “elements”–the raw things that haven’t had anything done to them.
