souriceau (French)
Where does "souriceau" come from?
The French word 'souriceau' follows a classic linguistic path, beginning with the Latin word 'sorex' for a shrew, which evolved into the Old French 'soris' before adopting the modern spelling 'souris' for mouse. This base was combined with the diminutive suffix '-eau', which traces back through Old French to the Latin '-ellus', a suffix originally used to denote young animals like piglets. Together, these roots transformed from a general term for a small rodent into the specific French noun for a charming 'mouseling' or young mouse.
