Did you know?
"Refractory" is from the Latin word "refractarius." During the 17th century, it was sometimes spelled as "refractary," but that spelling, though more in keeping with its Latin parent, had fallen out of use by the century's end. "Refractarius," like "refractory," is the result of a slight variation in spelling. It stems from the Latin verb "refragari," meaning "to oppose."
