Forms

rēniculus m (genitive rēniculī); second declension[1]

Etymology

It is formed from Latin rēn (“kidney”) + -culus, a diminutive.[2][3][4]

Earliest recorded meaning

Köbler's earliest source is the physician Theodorus Priscianus, about 400 AD;[5] Lewis & Short and Georges cite it from the medical writer Marcellus Empiricus, for a little kidney.[6][4]

Semantic evolution

It was a word of medical writers and remained rare.[6][5] In the plural it simply meant the kidneys, and the TLL lists Romance continuants of it.[3] It was sometimes confused with rēnunculus.[3][2] A British medieval prayer, the Lorica of Laidcenn, has reniculos among the parts of the body to be protected.[2]

  • c. 400 AD – Theodorus Priscianus has the word.[5]
