Did you know?

"Disinfectant on your hands keeps us healthier and fomites no longer foment as much disease." Australian newspaper contributor Peter Goers was likely going for alliteration when he paired up fomite and foment, a verb meaning "to promote the growth or development of"—but, whether he realized it or not, the words fomite and foment are related. Fomite is a back-formation of fomites, the Latin plural of fomes, itself a word for "tinder." (Much like tinder is a catalyst of fire, a fomite can kindle disease.) Fomes is related to the Latin verb fovēre ("to heat"), an ancestor of foment.
