Multilingualism is the act of using polyglotism, or using multiple languages, either by an individual speaker or by a community of speakers. Multilingual speakers outnumber monolingual speakers in the world's population. Multilingualism is becoming a social phenomenon governed by the needs of globalization and cultural openness. Thanks to the ease of access to information facilitated by the Internet, individuals' exposure to multiple languages is getting more and more frequent, and triggering therefore the need to acquire more and more languages.

People who speak several languages are also called polyglots.

A multilingual person, in a broad definition, is one who can communicate in more than one language, be it actively (through speaking, writing, or signing) or passively (through listening, reading, or perceiving). More specifically, the terms bilingual and trilingual are used to describe comparable situations in which two or three languages are involved. A multilingual person is generally referred to as a polyglot. Poly (Greek: πολύς) means "many", glot (Greek: γλώττα) means "language".

Nathaniel Adams Coles (March 17, 1919 – February 15, 1965), known professionally as Nat King Cole, was an American musician who first came to prominence as a leading jazz pianist. He owes most of his popular musical fame to his soft baritone voice, which he used to perform in big band and jazz genres. He was one of the first black Americans to host a television variety show, and has maintained worldwide popularity since his death.

Nathaniel Adams Coles was born in Montgomery, Alabama, on Saint Patrick's Day (March 17) in 1919. When he was 4, he and his family moved to Chicago, Illinois, where his father, Edward Coles, became a Baptist minister (Ruuth 31). Cole learned to play the organ from his mother, Perlina Coles, the church organist. His first performance, at age four, was of "Yes! We Have No Bananas". He began formal lessons at the age of 12, eventually learning not only jazz and gospel music but also European classical music, performing, as he said, "from Johann Sebastian Bach to Sergei Rachmaninoff".
