Carte blanche

Carte blanche is French for white paper (though blanche here more accurately means blank, and carte is versatile in French, allowing for several alternative translations such as blank map and blank ticket). In English, we use it as a figurative noun meaning total freedom to act or full discretionary power. A person with carte blanche is free to fill the figurative blank paper with his or her own rules and plans.

The loan phrase came to English in the 18th century. It caught on quickly, filling a gap in the language—it has few synonyms, though blank check sometimes comes close—and has been used consistently ever since.

The French plural is cartes blanches, but this rarely comes up in English because we usually treat carte blanche as a mass noun, meaning it takes no article and can’t be plural; we write “I have carte blanche” and “they were given carte blanche,” not “I have a carte blanche” and “they were given cartes blanches.”

The phrase was italicized in early use, but like most long-established loanwords and phrases, it now goes unitalicized.
