Use "toxic condition" in a sentence
"The suffix “osis,” on the other hand, merely denotes the presence of a condition e.g., thyrotoxicosis: the presence of a toxic condition of the thyroid gland; diverticulosis: the presence of pouches known as diverticula in the wall of the intestine … if, however, the diverticula become inflamed, we then have diverticulitis."
