What is quadrilingual?

Quadrilingual refers to a person who is fluent in four different languages. Being quadrilingual is considered to be a rare skill, as most people only speak one or two languages. Being able to speak four different languages can provide numerous benefits, such as increasing employment prospects, facilitating communication during travel, and broadening one's cultural understanding. It can be an advantage in a variety of career fields, including international business, diplomacy, and tourism. However, it requires years of practice and dedication to become quadrilingual, as mastering multiple languages is a challenging task.
