Relating to substances or treatments that are used to fight tuberculosis, a serious infectious disease that affects the lungs.
The doctor prescribed an antitubercular medication to help treat the patient's tuberculosis.
Antitubercular is formed from "anti-" (meaning against) and "tuberculum" (from Latin, meaning small swelling or lump, referring to the tubercle associated with tuberculosis). The word describes something that works against tuberculosis, a disease characterized by the formation of tubercles in the body.
Think of 'anti-' meaning against, and 'tuberculum' referring to the small lumps caused by tuberculosis — this helps you remember that antitubercular means something that fights against tuberculosis.
