What does dormice mean?
Dormice is the plural form of dormouse, referring to small, largely nocturnal rodents of the family Gliridae found across Europe, Asia, and Africa. Best known species include Britain's hazel dormouse, with its golden fur and thick tail, and the larger grey edible dormouse of continental Europe. What sets dormice apart from other mice-like rodents is their extraordinary torpor: they can hibernate for many months of the year, waking only briefly, and they move through trees with agile, sure-footed grace. The word itself is steeped in history — it may derive from French elements meaning 'sleeping' and 'mouse', and the Romans kept edible dormice in earthenware jars called gliraria to fatten them for feasts. Today, dormice appear most often in conservation contexts, as habitat loss has made them one of Britain's most closely watched protected mammals, and in literary memory through the perpetually drowsy dormouse at the Mad Hatter's tea party.

Etymology of dormice
The singular dormouse entered Middle English, probably via Anglo-Norman or Old French, as a blend suggesting both dormeuse ('sleepy female', from Latin dormire, 'to sleep') and the native word 'mouse' by folk association. The plural dormice simply follows the irregular mouse/mice pattern. The same Latin root dormire gives English cognates such as dormant, dormitory, and dormer, all carrying the sense of sleeping or rest.

How dormice is actually used
Dormice functions as an irregular English plural whose form mirrors 'mouse' → 'mice'; the singular is dormouse. The word carries a gentle, storybook connotation in British culture thanks to Lewis Carroll's sleepy dormouse in Alice's Adventures in Wonderland, but in ecological and conservation writing it is a precise technical term.
