Related to or forming a cavity or hollow space, especially in medical contexts like cavity formation in teeth or lungs.
From Latin cavus (hollow) with the English suffix -ary (relating to or characterized by). Medical professionals use this term to describe disease processes that create empty spaces in body tissues.
Cavitary tuberculosis was called the 'White Plague' because X-rays revealed hollow cavities eaten into the lungs—a word born from how disease quite literally makes holes in us.
