Italian Idiom of the Week: Essere farina del proprio sacco (to be one’s own work)

Have you ever created, designed or written something that you were extremely proud of because you did it all by yourself? If so, today’s Italian idiom is for you!


Italian idiom "essere farina del proprio sacco"

Essere farina del proprio sacco is a frequently used Italian idiomatic expression that describes something entirely of your own creation, something you managed to bring to fruition without anyone else’s help. Some other possible translations include:

  • to be the fruit of one’s own labour
  • to be one’s own doing

It is often used as a response when someone, such as a teacher or doubting relative, accuses you of copying someone else’s work, or when they doubt your abilities.

Here is how it is used with the various possessive pronouns:

  • è farina del mio sacco = it’s my work
  • è farina del tuo sacco = it’s your work (informal, singular)
  • è farina del suo sacco = it’s his / her work / your work (formal)
  • è farina del nostro sacco = it’s our work
  • è farina del vostro sacco = it’s your work (plural)
  • è farina del loro sacco = it’s their work


On the other hand, non essere farina del proprio sacco means that the person in question didn’t do something by themselves, or that they only managed to do it because someone else helped them.


You may be wondering what the literal translation of this idiom is. Farina means flour and sacco means sack, so literally we are saying “it isn’t flour from one’s own sack.”

According to Dizionario Italiano Olivetti, the expression comes from the latin non est de sacco ista farina tua.

Virgilio, on the other hand, explains that in the past, dishonest millers would add low quality flour to their sacks to sell it a higher price. In other words, some of that flour would not be their own, and that might be where the expression originated.
