The Charter of the French Language is a set of rules made by the government of the province of Quebec in Canada to protect and promote the French language. Imagine you have a special toy that you really love playing with, and you want to make sure it stays in good shape and no one takes it away from you. This is kind of like what the Charter of the French Language does for the French language in Quebec.
The Charter sets out rules about things like what languages signs can be in, how much French needs to be used in businesses and offices, and what languages can be used in schools. It also establishes the Office québécois de la langue française (Quebec Office of the French Language), which helps people learn and use French, and makes sure the rules of the Charter are being followed.
The goal of the Charter is to make sure that French is preserved and celebrated as an important part of the culture and identity of Quebec, even though there are many other languages spoken in Canada.
