From fūr (“a thief”) + -unculus (diminutive nominal suffix). The use of the ending -unculus, which more often appeared in diminutives of n-stem nouns, may be influenced by analogy with the word latrunculus (“highwayman, robber”), a diminutive with a similar meaning.[1] Alternatively (particularly in the sense "ferret"), could be from fūrō + -culus, i.e. a diminutive formed on an n-stem base fūrō, an alternative form of fūr.
