An official language is a language that is given a privileged legal status in a state, or other legally-defined territory.
A language is a method of communication. Human spoken and written languages can be described as a system of symbols (sometimes known as lexemes) and the grammars (rules) by which the symbols are manipulated. The word "language" is also used to refer to common properties of languages.An official (from the Latin Officialis, person – or object – related to an officium, see that article) is, in the primary sense, someone who holds an office (i.e. function, mandate, regardless whether it carries a working space with it) in an organisation, of any kind, but participating in the exercise of authority (either his own or that of his superior and/or employer, public or legally private). An elected official is a person who is an official by virtue of an election; officials may also be appointed, ex officio (i.e. by virtue of another office, often in a specified capacity, such as presiding, advisory, secretary), cooptated, or sometimes hereditary.
