Imprimatur is a noun that refers to a person’s acceptance or guarantee that something is of a good standard.

The Latin verb imprimere (Im pre MEER ay) means ‘to print.’ The Roman Catholic has historically printed an ecclesiastical and religious books as a means of given their approval to them. Since entering the English language in the mid 17th century, the word’s meaning has broadened and is now often used outside of the realm of religion. Here’s an example:

My favorite seafood restaurant offers gives the chef’s imprimatur on every dish. It’s great to see this man I respect giving his approval on their food.
