Etymology
FrenchEnglish
This phrase is a direct translation (calque) of the French expression 'cela va sans dire', which literally means 'that goes without saying'. English speakers began using this borrowed structure in the mid-1800s. The core idea — that something is so obvious it does not need to be spoken out loud — has remained unchanged since the phrase entered the language.
