squirrel: [14] The squirrel’s name means etymologically ‘little shadow-tail’. It comes via Anglo-Norman esquirel from Vulgar Latin *scūriōlus, a diminutive form of *scūrius. This was an alteration of Latin sciūrus ‘squirrel’ (now the scientific name for the squirrel genus), which in turn came from Greek skíouros, a compound formed from skiá ‘shadow’ and ourá ‘tail’.

squirrel (n.)youdaoicibaDictYouDict
early 14c., from Anglo-French esquirel, Old French escurueil "squirrel; squirrel fur" (Modern French écureuil), from Vulgar Latin *scuriolus, diminutive of *scurius "squirrel," variant of Latin sciurus, from Greek skiouros "a squirrel," literally "shadow-tailed," from skia "shadow" (see shine (v.)) + oura "tail," from PIE root *ors- "buttocks, backside" (see arse). Perhaps the original notion is "that which makes a shade with its tail." The Old English word was acweorna, which survived into Middle English as aquerne.
