Vaunt is a verb that means to boast about or praise something excessively.
The Latin word vanus (VAAH noos) means ‘vain,’ and that’s the birthplace of our word of the day, vaunt. The word later came to refer to praising someone excessively, usually in a way that may make them vain.
I always make sure to vaunt the salesman shortly after arriving at the car dealership. There’s something about an inflated ego that makes them a little more agreeable.
