nodule
Tiny rounded growth
A nodule is a small rounded lump or swelling.
The word appears in medicine for abnormal growths: The scan revealed a nodule on her thyroid.
In botany, nodules are the bumps on plant roots where nitrogen-fixing bacteria live.
Geologists use it for rounded mineral masses found in rock.
The diminutive form suggests something smaller than a node.
