What does miliary mean?
Miliary means resembling a grain of millet and is used primarily in medical terminology. Its best-known sense concerns miliary tuberculosis, a form of tuberculosis in which numerous tiny, millet-like nodules, called tubercles, develop in the lungs and may spread to other organs. The word can also describe lesions that resemble millet seeds because of their size or appearance. As a technical noun, a miliary is one such tiny tubercle. These uses belong mainly to pathology, radiology, and other clinical fields, so miliary generally has a formal rather than everyday character. Its unusual history lies in the comparison with millet: the adjective comes through Latin from milium, the Latin word for millet, the same source of the English word millet. In ordinary conversation, miliary may occasionally be confused with military because of their similar spelling, but their meanings are unrelated.
Resembling millet seeds, especially of a disease or lesion characterized by numerous tiny millet-like nodules.
"Radiologists identified diffuse miliary nodules in both lungs."
Chiefly used in medical and pathological contexts.
A tiny millet-sized tubercle, especially one occurring in miliary tuberculosis.
"Each miliary appeared as a pinpoint spot on the scan."
This is a specialized medical noun and is less common than the adjectival use.
The plural is used when referring to multiple miliary tubercles.
"Several miliaries were visible in the tissue sample."
A miliary lesion is named for its resemblance to a grain of millet—a tiny detail that helps explain why tuberculosis can spread through the body as countless millet-sized nodules.
