comestible

Did you expect comestible to be a noun meaning "food"? You're probably not alone. As it happens, comestible is used both as an adjective and a noun. The adjective is by far the older of the two; it has been part of English since at least the 1400s. In fact, one of its earliest known uses was in a text printed in 1483 by William Caxton, the man who established England's first printing press. The noun (which is most often used in the plural form comestibles) dates to the late 1700s.
