Etymology
Coined in the 1800s from Latin tuberculum ("small swelling") plus -osis ("diseased condition"), because the infection produces small lump-like nodules, or tubercles, in the lungs. For centuries before this scientific name existed, English simply called the disease "consumption," since it seemed to consume the sufferer's body away.
