What does nodular mean?
Nodular is an adjective describing a tissue, formation, or other material characterized by nodules: small, rounded masses or lumps. In medicine and pathology, a nodular finding may refer to a discrete growth within an organ or tissue, as in “nodular lesion” or “nodular mass.” The word also has applications in geology and other technical fields where formations contain small knot-like bodies. It is distinct from the noun “nodule,” which names such a mass, and from the general adjective “lumpy,” because “nodular” is more precise and strongly associated with specialized descriptive terminology. Doctors may use it when describing the shape or arrangement of abnormal tissue, while mineralogists and geologists use it for structures with small, rounded components. Because the word conveys a specific physical form rather than a diagnosis, it should not be taken to mean that a condition is cancerous or otherwise dangerous without additional clinical information.

Where does nodular come from?
“Nodular” was formed from “nodule,” with the suffix “-ar,” and developed within English’s scientific vocabulary for describing structures made up of nodules. “Nodule” comes through Latin nodulus, a diminutive of nodus, meaning “knot.” Related English words include “node,” “nodosity,” and the now less common “nodulose,” all reflecting the same Latin foundation associated with knots or rounded projections.
