Edible If its edible, you can eat it. Many things that you may not want to eat are, in fact, edible. Certain insects are edible, which just means that you can consume them without getting sick (if it doesnt gross you out too much). Edible comes from the Latin word ed-ere, which means to eat. Anything that people can safely eat is described as edible. Long before there were complex labels on our packages of food, human predecessors were living in caves and sampling various plants and animals for their survival, all the while learning the hard way whether or not certain things were either edible or poisonous. You are most likely a descendant of the ones who found the edible stuff.
