The Story Behind It


As a habitual over-packer whose handbag feels more like workout equipment than an accessory, I can’t help but associate this expression with the feeling of relief I get when I empty said bag. But okay, okay. That’s not the real story here!


The truth is, far greater minds than mine have determined other origin stories for the French expression vider son sac. One of the most commonly cited takes us back to the 17th century, to the courthouses, where lawyers would empty bags containing rolled-up supporting documents and evidence before pleading their cases. When a case was closed, the lawyer’s files were returned to the bag and the affair was said to be dans le sac (“in the bag”).


But the folks at Expressio.fr also propose a second theory—this time attributable to the famous linguist and lexicographer Alain Rey and scatological in nature. Rey has suggested that vider son sac was a euphemism for defecating, with sac referring to the stomach. The relief in emptying one’s bowels was then linked to the relief in speaking one’s mind. Charming!
