What does tubercular mean?
Tubercular is chiefly an adjective meaning relating to, caused by, or affected with tuberculosis, the bacterial disease caused by Mycobacterium tuberculosis. In medical contexts it can describe lesions or other pathological features associated with the disease; established expressions include “tubercular lesions,” “tubercular disease,” and “tubercular meningitis.” More generally, the word can mean covered with or resembling tubercles, which are small nodules or swellings. Its use as a label for people has largely fallen out of favor outside historical or specialist writing. Modern medical English more often uses “tuberculous,” as in “tuberculous meningitis,” or identifies the condition directly. As a dated noun, tubercular can mean a person with tuberculosis, but this use belongs mainly to older medical and literary records. The word is therefore most useful today as a precise medical adjective, while its older literary associations reflect the stigma once surrounding tuberculosis and its treatment.

Where does tubercular come from?
Tubercular entered English in the 17th century from Latin tubercularis, meaning “of or like a tubercle.” Its ultimate root is the Latin tuberculum, a diminutive of tuber, meaning “swelling” or “lump.” The same root underlies tubercle, tuberculosis, tuberculin, and tuberculous.
How tubercular is actually used
The adjective remains legitimate in specialist medical contexts, although “tuberculous” is often more idiomatic when describing a person or lesion. “Consumptive” is a dated synonym. The noun use is chiefly historical or literary and should not be used as a substitute for the more specific term “person with tuberculosis.”
