“Take something with a grain of salt”in other languages

Same idea, different pictures

English is often traced to Pliny the Elder, who recommended taking an antidote “with a grain of salt”. French says it's sujet à caution, subject to a guarantee: not to be believed without one.

Italian accepts it con beneficio d'inventario, with the benefit of inventory. In Roman law, an heir could accept an inheritance only after listing what it contained, so as not to inherit hidden debts.
