2. Bilingualism
is commonly defined as
the use of at least two languages by an
individual (ASHA, 2004). It is a
fluctuating system in children and adults
whereby use of and proficiency in two
languages may change depending on the
opportunities to use the languages and
exposure to other users of the languages.
It is a dynamic and fluid process across a
number of domains, including
experience, tasks, topics, and time.

4. Multilingualism
is the act of using
polyglots, 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. 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.
