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."
