Multilingualism is the use of multiple languages or at least more than one language (usually is the mother tongue or language), either individually or in groups in many fields. A multilingual person or commonly known as polyglot is a person who knows, understands and uses more than one language. A polyglot may speak many languages but not be able to read or write them. Multilingualism in general is very helpful in many fields, making more people more connected and reducing misunderstanding. That way, many things can be done easily and smoothly. It is no wonder why multilingual education is becoming more common nowadays. There are several parameters that can be used to measure multilingualism, I will write about this later.
