Persian Rugs, not Parisian

There are many words in the English language that look and sound similar but mean something totally different from one another. For example, reign and rein are often mized up. Reign is the sovereign rule of a monarch or someone else in a position of power. They "reign" over the land. Reins, on the other hand, are those little tethers that you yank on to make a horse do what you want it to do. People mix them up all the time, like saying "i'll take over the reigns". That's quite incorrect.
Another example is regimen/regiment. A regiment is an organizational unit within the United States Military, usually comprised of hundreds or thousands of marines or infantrymen. A regimen is a new training schedule you'd like to stick to. A new regiment might have a mile-running regimen. I have a new beauty regimen to keep my skin looking young. Afghanistan has a new regiment of foot soldiers.
So, a Parisian rug is a rug from PARIS. A Persian rug is from PERSIA, or Iran in today's terms. If you type out that you have a Parisian rug, maybe you mean you bought that rug in Paris. Not that it is a middle-eastern woven antique rug. There is a massive difference in styles and expectations about rugs from those two areas. Persian rugs have a very specific aesthetic, certain patterns and colors, etc. A Parisian rug could probably be about anything. It could be a bright orange rug with purple polka dots. (Let's hope it's not.)
So don't make these sad mix-ups! English is hard but these fine distinctions are important for clarity of communication.
