Anagrams

Latin

Alternative forms

• mīcca (attested in 1485, Du Cange)

Etymology

Uncertain:

• traditionally derived from Proto-Italic *(s)mīkā, from Proto-Indo-European *(s)meyk- (“small, thin, delicate”), related to Ancient Greek (σ)μῑκρός ((s)mīkrós) – details there.
• in view of meaning (1), De Vaan (2008) with Nyman (1987) prefer Proto-Italic *meikā (“a glittering particle”), from Proto-Indo-European *meyk- (“to blink”), whence also micō.

Attested from Cato onwards.

A number of Romance forms, e.g. Romanian mic, Neapolitan miccu, Calabrian/Sicilian miccu, reflect an unattested adjective *mīccus. This is probably unrelated, being a borrowing from Ancient Greek μῑκκός (mīkkós), variant of μῑκρός (mīkrós, “small”); the form *mīcca is associated with the meaning “loaf of bread” particularly in Gallo-Romance and Gallo-Italic.^[1]
