French is the second language of Lebanon, and is often used as a prestige language for business, diplomacy, and government, alongside English.
The use of the French language is a legacy of the time of the French Crusades and France's historic ties to the region, including its League of Nations mandate over Lebanon following World War I; as of 2004, some 20% of the population used French on a daily basis.
Formerly under French mandate, Lebanon designates Arabic as the sole official language, while a special law regulates cases when French can be publicly used. Article 11 of Lebanon's Constitution states that
"Arabic is the official national language. A law determines the cases in which the French language is to be used".
The French language is also used on Lebanese pound bank notes, road signs, vehicle registration plates, and on public buildings, alongside Arabic.
The majority of Lebanese people speak Lebanese Arabic, which is grouped in a larger category called Levantine Arabic, while Modern Standard Arabic is mostly used in magazines, newspapers, and formal broadcast media. Code-switching between Arabic and French is very common.
Lebanese Sign Language is the language of the deaf community. Almost 40% of Lebanese are considered francophone, and another 15% "partial francophone," and 70% of Lebanon's secondary schools use French as a second language of instruction. By comparison, English is used as a secondary language in 30% of Lebanon's secondary schools. The use of Arabic by Lebanon's educated youth is declining, as they usually prefer to speak in French and, to a lesser extent, English, which are seen as 'hipper'.
