The Origin of Tonsillitis or Strep

The word tonsillitis comes from “tonsil” (lymph tissue in the throat) and “-itis,” a Greek suffix meaning inflammation. It literally means “inflamed tonsils.”

The word strep comes from Streptococcus, a Greek term meaning “twisted berry,” describing how the bacteria looks under a microscope. Doctors shortened it to “strep” for easier use in clinics and schools.

These medical terms became common in the 19th and 20th centuries when throat infections were studied more deeply.
