Comestible is an adjective that means ‘edible.’ It is also a noun that refers to ‘food.’
The Latin word comedere (co may DARE ay) means ‘to eat’ or ‘consume.’ By the 18th century, it had evolved into its present form to mean ‘fit to eat.’ As an adjective, comestible holds roughly this same meaning. As a noun, the word made its first appearance in print about a century later.
I sure wish that wax fruit on my desk was comestible. Right now, I’m hungry enough to sink my teeth into anything that can be eaten.
