Explanation: The word bilingual comes from Latin and was added to English from French, when the Duke of Normandy conquered England in the battle of Hastings (1066) and both the king and the nobles used French as their usual language. Little by little, they began to learn English and became "bilingues", which in Latin means bis = two, lingues = languages, which literally means "the one who has two languages", which can be interpreted in two ways. That someone expresses himself in two different languages and also that someone is a hypocrite, deceitful and treacherous. Nowadays, bilingual means "the one who uses fluently two languages. If someone uses many languages, it is called polyglot.
