3. Most people in the world use more than one language.
“Over 50 per cent of the world’s population function in two or more languages on a daily basis. In other words, multilingualism, not monolingualism, is the norm. There are many reasons why someone might be bi - or multilingual: having parents who speak two languages; moving abroad to work; political migration, where individuals and families need to learn the language of a new community while maintaining links to the home country; education, where children pick up foreign or second languages at school; bi - or multilingual communities, where individuals switch between languages on a daily basis; and historical events, such as the 'discoveries’ in the 15th and 16th centuries that led to colonialism, where the language of the coloniser was adopted by the people, and continues to survive in a local variety.”
