[L. rānula a little frog, a little swelling on the tongue of cattle (Vegetius), dim. of rāna frog. Cf. F. ranule.]
A cystic tumour under the tongue, caused by the obstruction of the salivary ducts or glands.
‘The term is derived either from an imaginary resemblance of the swelling to a frog, or from the peculiar croaking noise which the patient makes when affected by it’ (Craig).
