Linguistics is the scientific study of language, and involves an analysis of language form, language meaning, and language in context. The earliest activities in the documentation and description of language have been attributed to the 6th century BC Indian grammarian Pāṇini, who wrote a formal description of the Sanskrit language in his Aṣṭādhyāyī.
Multilingualism is the use of more than one language, either by an individual speaker or by a community of speakers. It is believed that multilingual speakers outnumber monolingual speakers in the world's population. More than half of all Europeans claim to speak at least one language other than their mother tongue; nevertheless, many of these are monoscriptual. Multilingualism is becoming a social phenomenon governed by the needs of globalization and cultural openness. Owing to the ease of access to information facilitated by the Internet, individuals' exposure to multiple languages is becoming increasingly frequent, thereby promoting a need to acquire additional languages. People who speak several languages are also called polyglots.
