Etymology
The word 'ranula' is a direct borrowing from Latin, where it literally meant "a little frog". This vivid anatomical metaphor arose because the bluish, fluid-filled cyst under the tongue was thought to resemble the throat pouch or the shape of a small frog. The Latin root rana (frog) is of uncertain deeper origin, though it may be echoic of croaking. The diminutive suffix -ula was commonly used in medical Latin to form descriptive terms for small structures or lesions. Thus, the term's logic moves from a visual analogy (a frog-like swelling) to a precise clinical descriptor for a specific sublingual cyst.
