grenouille (French)

Where does "grenouille" come from?

The French noun 'grenouille', meaning 'frog', is inherited through Middle French '(g)renouille'[1] and Old French '(g)renoille'[1][3] from the Vulgar Latin reconstructed form '*rānucula'[1][3]. This Vulgar Latin term originated as a diminutive of the Latin word 'rāna', meaning 'frog'[1][3][4], which itself is likely onomatopoeic and mimics the croaking sound of the animal[2].

Open questions

• The Vulgar Latin form '*rānucula' is a reconstructed intermediate form rather than an directly attested ancient spelling. [1] [3]
