Usage
What does numero uno mean? Numero uno means number one and is used in most of the same ways that number one is used.It’s commonly used to refer to oneself or one’s best interests, as in He always looks out for numero uno before even thinking of helping other people. It’s also commonly used to refer to someone or something that is the best or highest in rank. In this way, it can be used as both a noun (as in They’re numero uno, and there is no close second) and an adjective (as in We hold a national championship game because we want the nation’s numero uno team to be determine by a head-to-head matchup, not a ranking committee).Numero uno comes from Italian, in which it literally means number one (the Spanish phrase número uno is pronounced the same way and means the same thing). Like many other Italian and Spanish words and phrases that have been adopted into English, it is often used in a very informal way to sound cool or to be humorous.Example: She’s the GOAT, the best, numero uno—no one will ever rise to her level of greatness.
